Form layout and CSS classes - Formidable Forms

Knowledge Base → Styles → Form layout and CSS classes

The easiest way to place multiple fields in a row and design the layout of your form is to use the many CSS layout classes offered by Formidable. You can add these CSS layout classes to individual fields or add them to Section Headings to organize large groups of fields.

Add a CSS layout class

Go to edit your form.
Click on any field and open the Field Options → Advanced section in the left sidebar.
Click the menu icon in the CSS layout classes box.

When you click the menu icon in the right side of the box, the Add Layout Classes settings will be shown below it. This gives you a complete, clickable list of all the layout classes which you may use.
Click any of the classes in the Add Layout Classes settings to insert them into the CSS layout classes box.

You can use multiple classes by inserting a space between each class. Example: 'frm_first frm_half'

Example

Here's an example of the output you can achieve with adding classes.

Add a form layout

To align multiple fields on the same row with a form layout, follow these steps:

Drag and drop the fields into the form builder and align them on the same row.
To adjust the layout of your form fields, hover over the field group and click on the Set Row Layout icon. You will then have access to a list of different layout options to choose from.
If you prefer a custom layout, click on the Custom Layout icon and use the 12-column grid system to enter the number of columns for each field. It's that easy!

Add columns in a form

Creating columns in a form is as easy as adding a CSS layout class to your fields.

For more advanced form layouts, consider using the layout field action, which offers a more straightforward approach with its drag-and-drop functionality. It's important to note that the CSS Layout classes mentioned in this guide are still compatible and supported.

Add fields to your form. Alternate between adding a field for the first column and a field for the second column. Every other field will be in a different column, so order your fields with that in mind.
Open the field options for each field that should be in the first column. Click the menu icon in the CSS layout classes box. In the Add Layout Classes settings (left sidebar), click the First style class and the 1/2 button. This will insert the frm_first frm_half classes.
Open the field options for each field that should be in the second column. Click the menu icon in the CSS layout classes box. In the Add Layout Classes settings (left sidebar), click the 1/2 button. This will insert the frm_half class.

Section heading columns

— Premium Feature —

You can use the layout field action to create section heading columns. To position two section fields side by side, drag and drop them in the form builder. Then, add your preferred fields to each section.

Using Section Headings can be a much faster way of creating a two-column form because you only need to add classes to the Section Heading fields instead of every field in the column.

Add a Section Heading field to your form. This will be for your first column. Open the field options and click the menu icon in the CSS layout classes box. In the Add Layout Classes settings (left sidebar), click the First style class and the 1/2 button. This will insert the frm_first frm_half classes.
Add another Section Heading field to your form. This will be for your second column. Open the field options and click the menu icon in the CSS layout classes box. In the Add Layout Classes settings (left sidebar), click the 1/2 button. This will insert the frm_half class.
Add fields that you want in the first column to the first Section field.
Add fields that you want in the second column to the second Section field.
If you don't want the Section Heading text to be shown in your form, set the Label Position to hidden or none on both of your Section Headings.

Create natural language forms

Natural language forms go by several names including Mad Libs style forms. These types of forms include form fields inside of a sentence. They often use styling that shows only a blank line rather than a text box, similar to the available Mad Libs Lines style template.

To create a form like this, follow these steps.

Add a section field to your form for each sentence or block of text. Set the label position to none.
Alternate HTML fields with other field types inside the section. The HTML fields are for the text between the other fields. Set the label position on each field to none.
If there are any fields followed by a period or comma, add no-right-margin into the CSS layout classes box for that field.
Go to the Settings → Customize HTML and add 'frm_madlib' into the Form Classes box.

Go to the Formidable → Global Settings → Custom CSS page and add this css:

.frm_madlib .frm_section_heading {
display:flex;
flex-wrap: wrap;
align-items: flex-end;
}

.frm_madlib .frm_section_heading div {
margin: 5px;
}

.frm_madlib .frm_section_heading div.no-right-margin {
margin-right: 0px;
}

Create a new style or import the Mad libs line style template. See how to only show the bottom border in a field.
You're all done. Your form should look like the form in the screenshot above.

Create custom mobile-friendly form

All forms created with Formidable Forms are mobile-friendly and responsive. By default, the fields will be displayed in a single column on mobile. If you want to customize how many fields will be shown per row, you can follow the steps below.

These instructions are specific for Bootstrap 3. Follow this guide if you plan to migrate to Bootstrap 5.

Install and activate the Bootstrap styling add-on. This add-on is included in the Formidable Plus plan and higher.
Go to Formidable → Global Settings → General Settings, and choose 3.3.7 as the Bootstrap version.

Go to your Formidable → Global Settings → Custom CSS page and add this:

.frm_fields_container {
    display: block !important;
}
.with_frm_style .frm_form_field {
    clear: none;
}

Add three fields to your form. Insert col-xs-4 as the CSS layout class for each field.
If you view your form on a mobile device, you should see three columns even on small screens.
Learn more about the other Bootstrap layout options available.
- col-xs-6: Display two fields side by side.
- col-xs-6 col-md-4: Display three fields side by side on bigger screens, and two fields side by side on smaller screens.

Migrating from Bootstrap 3 to Bootstrap 5

If you are migrating to Bootstrap 5, it is important to note that the col-xs-6 class is no longer supported and has been replaced with col-6. This change applies to other xs columns, as the -xs has been removed. Follow the steps below to get started.

Replace instances of col-xs-6 with col-6 or col-xs-4 with col-4 in your field options CSS Layout Classes box.
If you haven't already, remove the old custom CSS added using the Bootstrap 3 guide.
Add the filter and custom CSS from the Bootstrap 5 guide.

Make mobile-friendly forms with Bootstrap 5

With Bootstrap 5, you can create mobile-friendly forms using flexbox. Learn how to build layouts with the flexbox grid.

Install and activate the Bootstrap styling add-on. This add-on is included in the Formidable Plus plan and higher.
Go to Formidable → Global Settings → General Settings, and choose 5.0.2 as the Bootstrap version.
Add this code snippet to your site. To learn more about how to use code examples like this, see the Formidable Hooks guide.
```
add_filter(
	'frm_fields_container_class',
	function() {
		return 'class="frm_fields_container row"';
	}
);
```
In the Formidable → Global Settings → Custom CSS page, add a custom CSS like this:
```
.frm_fields_container {
  display: flex !important;
  grid-gap: 0 !important;
}
```
To optimize the layout of your form on mobile devices, you can add three fields with a CSS layout class of col-4 for each field.

It will ensure that your form will display three columns, even on small screens.
Learn more about the other Bootstrap layout options available.
- col-6: Display two fields side by side.
- col-6 col-md-4: Display three fields side by side on bigger screens and two fields side by side on smaller screens.

Create an inline form

If you want to customize your form layout and create an inline form where all the fields are aligned in a row, follow the steps below.

Create a new form or edit an existing one.
Add the fields where you want to apply the inline formatting. In this example, we will add a Name field and Email field. By default, these fields are stacked.
Use our drag-and-drop layout builder to move the fields in a row.
To make room for the submit button in the 12-column grid, hover over the row and click the Layout icon right above the row.
Click Custom Layout and change the value to 6 and 3. Alternatively, you can use the CSS Layout Classes box to add frm_first frm6 for the Name field and frm3 for the Email field.
In your form builder, click the Submit button to open the field options. In the Submit Button Position dropdown, select Inline.
To line up the submit button to the form fields, go to form Style page. Click the New Style button and create a new style called Inline Style.
Look for the Button section and change the padding to 6px 20px. Click the Update button to save.
Go back to the form Style page. Select lnline Style and click the Apply link.

You're all done! Your inline form should look like this.

More layout customization

Users familiar with HTML can further customize the form layout by using the Customize HTML tab on the form settings page.
