Checking/ Unchecking a list of items with checkboxes is provided with a master checkbox to provide ease to users to control all list items. Angular Material Checkbox module MatCheckbox proves very handy in creating such lists with a number of properties.
In Material Checkbox module there are three states with Checked and Unchecked which are common, but there is also a third state called Indeterminate which is a middle of these two. Indeterminate Checkbox state indicates that some of the list items are checked but not all. It is indicated with a hyphen (-) in the checkbox.
Here we will create a list of items with a master checkbox using which a user can check to uncheck all item lists. Also if a user checks some of the items but not all, the master checkbox will show Indeterminate state which is very easy to implement.

In Ionic we have a Native Plugin SQLite which can be easily integrated with the application and have no limitation on storage of data, it depends on device memory.
SQLite is SQL based database where we can easily create databases, tables, and store or retrieve complex data from it by running SQL queries.
