Linked list only select

hello every one

my problem here . i want to select item or project or customer in related doctype but not enter to customer page when i click on it or the item just select it only without having accesses on item master
any suggestion

In that case, there is no need for the field to be a Link field. It can instead be a Select field, with the options fetched dynamically with a client-side script.

thanks for speed help i will try
