ExtJs Grid has a lot of features built in. Some examples are the Grouped Grid and the Checkbox Selection.

However, grouping these two together poses a bit of a challenge.

After searching on the forums, this post guided me into a nice, working example.

ExtJs does have a attribute for required by the allowBlank configuration against fields.

However, this configuration doesn’t have a setAllowBlank or a getAllowBlank method, because of which, it is not possible to bind those fields via the viewModel. So, usually, those fields have to be somehow fetched in the Controller and then that attribute.

This situation can however be remedied very easily.

ExtJs, by default, doesn’t provide a month picker.

A monthfield picker allows you to choose specific months only.

The customization that was required, was to have a start date and an end date for those months, so that at the end of the operation, those specific dates could be saved.
