In our existing application, we use combo with coro cell type. We do this using Initialization from XML “For separate cells (pro version only)” method. Below is the link I am referring to
docs.dhtmlx.com/grid__managing_s … ction.html.
We got a change in our application to add categories to that combo. I tried adding optgroup in the following way. But it didn’t work and xml loading failed. Can you please let me know the correct way of achieving this.
