My object tab contains a lot of select fields with a lot of options in each field. When I switch to the tab - browser hangs, CPU usage is 100% and I have to wait a minute or so until the tab is finally rendered. The same behavior is when object bricks has a lot of select elements or classification store.
I think that PIMCore creates such elements on the fly and uses EXTjs instead of regular html selects.
Please push me in right direction to fix this. Maybe do select elements without JS and style it to have the same look as other elements.
Help me, please. This issue is really killing my project at the moment. I cannot present it to the customer and I cannot remove options or remove some elements as all data is required to be inside PIM.
