Hide the form
In some circumstances, you may wish to have a form live (accessible), but not shown in your site's search or category lists. This can be achieved by setting the Visible toggle to off.
If you don't already have the form open, begin by finding your form in the form list and click on the title to open the form.
With the form open, you'll be on the Pages tab and will see the form structure. Click the Publish tab to open up the Publish tab. If this is not enabled, you first need to add a page to your form.
Toggle Visible, so that the toggle goes grey (off position).
The Publish tab will save this automatically. Once it is saved, the Save button will read Saved and turn green momentarily.
