I have several custom fields that have many options and would take up considerable vertical space to list. I would like to style the search fields so that the search field name is in the header of accordions and upon expansion would list the relevant checkboxes. Attached are screenshots of the current view (site is still in development) and the desired outcome.
Toolset doesn't yet have an accordion block, you would need to use a 3rd-party solution, such as Kadence blocks.
You should be able to add accordion blocks to the search filter section of your View and drag and drop the search filters into place as required.
You'll need to set the accordion titles manually. To avoid the titles being duplicated, in the settings for the filters you can opt not to show the label.
