I have a form which has a category field type dropdown. when a category is selected from a dropdown i want it to populates another field called 'credits' based on the category that was selected. the credit value is store in the category table along with the category name.

Any help would be great.

This is going to be something you want to do with javascript. The backend already implements jquery, if you're familiar.

Here is an thread about custom js https://octobercms.com/forum/post/how-to-add-javascript-file-to-backend-pages

something along the lines of

$(document).ready(function() {
    $('#dropdown').change(function() {
        var val = $(this).val();
        switch(val) {
            case 'first':
                $('#credits').val(2);
                break;
            case 'second':
                $('#credits').val(3);
                break;
        }
    });
});
