Fluent Forms offers Taxonomy Fields that allow you to group your posts based on categories, tags, and other taxonomies available on your WordPress site.
Remember, you will get this Taxonomy Fields Module only in a Post Form. You can also use your own Custom Taxonomy Fields. To learn how to add custom Taxonomy Fields, read this Documentation.
This article will guide you through adding the Categories Taxonomy Field in your Fluent Forms for your WordPress Site. This Categories field will allow your users to select any of your existing categories and submit their posts under the selected category directly through the form.
Add Categories Field #
To learn how to add the Categories field to the Post Forms in Fluent Forms, follow the steps with the screenshots below –
First, go to the Forms section from the Fluent Forms Navbar, choose a desired Post Form, and click the Pencil/Edit icon to open the Editor page of that form.
If you don’t have an existing Post Form, read this Documentation to create a new one. For example, I choose an existing Post Form to show the whole process. Remember, you will only get the Categories field under the Post Forms.

Once you are on the Editor page, go to the Input Fields on the right sidebar and open the Taxonomy Fields dropdown list by clicking the Arrow Icon. Now, choose the Categories field by clicking on it or Drag & Drop it into your editor.

Customize Categories Field #
You can see that a Categories field is added to the form. You can Edit or Customize this field by hovering over it and clicking the Pencil Icon.
It will take you to the Input Customization tab on the right side and offer you the following options for customizing the field.
- Categories
- Advanced Options
