I need to create component like combobox but instead of plain list there should be tree. I tried to implement it by modifying Ext.form.field.ComboBox but I was lost while creating picker.
Is there simple way to create this type of control? I don't need validation, showing selected value inside the tree and so on.
I just need only edit box with button. By pressing on this button the picker appear with tree we select something and the value inserted to the edit box. I can't use separate window for tree, because in this case the editbox loses the focus and property grid destroys the editor
