Hello!
How i can add arrow like this for my interface parameter?

In the Type Properties dialog, select the parameter you'd like to add the button to, and under the Action Button tab, you can add something like:


On the Parameter tab, you might or might not also need to add 3 entries in the Tags table (where the last entry's text is multiple lines). It might or might not be automatically filled in if you just fill in the Action Button tab, (I'm not an expert on that front).

script_action_icon    BUTTONS_reselect
script_action_help    Select geometry from an available viewport.
script_action         import soputils
kwargs['geometrytype'] = hou.geometryType.Primitives
kwargs['inputindex'] = 0
soputils.selectGroupParm(kwargs)

Thank you very much.
