grid filtering with regular expression

Hi,
I have a grid with one column with values ‘A’,‘T’,‘B’.

I have an attachHeader with the possibility to #select_filter the three different values.

Now I want to be able to select different possibilities with a regular expression for example or chechboxes in the header (like you have in excel). I want for example to be able to select A and T, but not B.

I tried with the filterBy function, but I don’t know where to start.

can someone help?

Unfortunately there is no multiselect filter in the dhtmlxGrid.
You may try to use the filterBy method:
docs.dhtmlx.com/grid__filtering. … cfiltering
or create your own custom filter with the required logic.
