Add an "ALL" button on my Checkbox list

Hi Corvid Team,
I have created a checkbox list to give opportunity to my customer to make multiple seection, however I would also like to give them opportunity to select all choices once at a time by clicking on “All” button box. Could you help mewith the specific code required for this option?
Regards.

You can just add another checkbox option called All . Then when the user selects All you just clear the filter.

Thanks for answering Yisrael. However I would like to know if you can share with the corvid link or the code necessary to make this function happens.
Regards.
