Relationship initial_filter

Good day guys. I have 2 relationship in my module , the model_description and color. After I select model_description, I need to extend the popup query. I need to fetch colors having the model_description ID that i have selected. How can I achieve this?

Please tell me know if you have any clarifications. I am using v7.10

Would this work for you?

Im sorry but as per requirements, it will not be possible.

By the way, do you know how to add initial_filter but referring to a relationship table?


'initial_filter' => '&column_name_from_relationship_table_advanced="+encodeURIComponent(document.getElementById("model_description").value)+"'
