Sharepoint List columns required

Hi,

According to your description, my understanding is that you want to set the other field required if the dropdown list value is 2.

I suggest you can use Jquery Validate Plugin to achieve it. You can place the Jquery code under the PlaceHolderMain tag in the New/Edit form page.

Here is a code snippet for your reference:

More information:

b: {
    required: {
        depends: function(element){
            return $("#dropdownlist").val()=="2"
        }
    }
}
c: {
    required: {
        depends: function(element){
            return $("#dropdownlist").val()=="2"
        }
    }
}

d: {
    required: {
        depends: function(element){
            return $("#dropdownlist").val()=="2"
        }
    }
}

e: {
    required: {
        depends: function(element){
            return $("#dropdownlist").val()=="2"
        }
    }
}
