[Pro Form] How to set conditionally display any form field when a single checkbox field is checked in a checkbox field wrapper

Hi everyone, how to conditionally show any field when a single targeted checkbox field is checked in a multiple checkbox wrapper field?

Below is the example, when “Others checkbox field” is checked, “Others Textarea field” should display.

In the condition settings, how can target the “Others checkbox field”? Below screenshot is an incorrect way of attempting

I wish this was more clear how to do - i have been trying different IDs for an hour but nothing works.

I figured my error out at least (sorry to necro this but i really thought we had the same issue)

In the console on my page i had this error:
2025-08-29-210158_hyprshot

As far as I can tell now this was caused by a gravityforms form being on the same page - the two conflict with one another. I was simply using it as a reference to build the same form in bricksforge. Once I removed the gravityform the console error went away and my conditionals started working.

While I’m here, and since this is not in the documentation or stated completely clearly in any forum posts either, here is how to make a checkbox conditionally display other form fields:

  1. Copy the “Custom ID” of your Checkbox Wrapper (First item in the General tab)
  2. Select the field you want to conditionally show
  3. Select the “Conditions” tab in the lefthand menu
  4. Click “Add Item”
  5. Choose “Form Field” in the Condition select box
  6. Paste the “Custom ID” into the next field

From here it’ll start getting custom to your site, but here’s a couple of working examples:

For a checkbox wrapper that contains multiple fields:
Choose “Contains” and paste in the checkbox value in the field below that

For a single checkbox (or to mean ANY checkbox within the wrapper):
You could choose “Is Not Empty”
