How to do binding for the checkbox? together with the user input if they choose other here? can anyone help?
回答1:
The simplest implementation will be with Multiselect Widget. However, it will look slightly different:
Model
Designer
Note, strToArray transformer is used in the values binding
Runtime
For sure, you can go fancy customizing look and feel of the Multiselect with CSS or playing with input's visibility basing on selected values and so on...
