is it possible to limit the amount you can select in the list builder?
I have over 200 in the list but I only want the client to be able to select a maximum of 5 or 10 at a any one time
Not that I know of. But you could try counting the number of “filled” rows output by the listbuilder. If it’s over 5 then return an error message to the user and reset the component.
But that won’t trigger until the user has finished making a selection and hit UPDATE. Not ideal, but it might work.
