Mass select in relationship panel

[kacper]

Hello
is it possible to add mass select to the relationship panel as is the case with a regular list of entities? Something like the image below

It is depending on the relationship you create. If it is 1:n you will have the possibility to link more than one related record to the parent entity. If t is n:n, the same. If it is n:1, you may choose only one related record.

Thanks for answer, I have m:n relation. So how to add this checkboxes? I've tried add "massSelect" but it doesnt work

it is not really clear. From your screenshot, I do not see the link field,created by the relationship. You have to place it in the layout.

I believe you can only do it from the ... menu
