I have some questions about component.
You’d better know about ‘filter component’ what i said.
It is component layer popup what is comed up when you click gear wheels icon in header cell of row or column.
I’ll wait your reply.
Thank you for posting to our Support Forum.
In Flexonster it is possible to turn off all filters at once by setting
showFilter option as
false(both for columns and rows).
In your case, we can suggest creating your custom Filter Window. This is possible via filteropen event. Please have a look at the following example: https://jsfiddle.net/flexmonster/9opghpko/. It hides the default Filter Window using CSS and JS. At line 34, instead of the alert, you can create your custom pop-up.
Hope it helps.
