I have created one section with the name of Courses and added one lookup for selecting the contact. For this lookup, I need to implement a multi-select lookup. Can anyone please guide me?
This question was already discussed in community post: https://community.bpmonline.com/questions/multiselect-lookup so you can simply use the solution from there.
Also there is a base realisation of multi-select in "Customer" field of an "Opportunity" page http://prntscr.com/oys5pc so you can simply review the logic that is used for that field and simply apply it to your custom lookup.
Thank you Oscar Dylan.
But, Where I can find that lookup.config?
You need to develop one using Academy article here

Actually, What I am asking is Can we implement a multi-select lookup for a field in the section?
I have one section. In that, I have created one lookup field. For that lookup field, I need to implement multi-select lookup.
