Search In Categories In Vendor Page [When Adding A Product]

Hello there,

I am trying to set up my MVE shop.

I have over 2.500 categories where vendors will add their products to. The thing is, is there any way to implement or activate category search when vendor is adding a product?

For instance vendor wants to add X category to newly created product. This X category is like child of 1 / 2 / 3 / 4 / 5 / X. So vendor has to search for this with only drop-downs.

Instead is there a way to simply write and search inside categories?

Thanks!

I am afraid, it is not possible without additional code modifications of picker with categories list
