I developed a widget for find any value from a related model, it’s simple; most of times we chose a value from
a combo box, but, it’s easy when the size list options is small, however when this size is very large, the choice becomes difficult.
This widget is a structure : Textbox for input, a label, and a linked image to push, when the user do it, show a modal window that contains a Grid with a list of records from the model to find , with all fields to filter, the user can select a value, then the window close and this value is copied into textbox, in addition the value text belongs to selected value is copied too into the label from originally window.
Use this widget is very easy,
