Data table - Selection
Item value
For the selection feature to work, the data table must be able to differentiate each row in the data set. This is done using the item-value prop. It designates a property on the item that should contain a unique value. By default the property it looks for is id.
You can also supply a function, if for example the unique value needs to be a composite of several properties. The function receives each item as its first argument.
Selected values
The current selection of the data-table can be accessed through the v-model prop. The array will consist of the unique values found in the property you set using the item-value prop (or the value returned by the function you passed). You can use return-object prop if you want the array to consist of the actual objects instead.
Examples
Selectable rows
Use the item-selectable prop to designate a property on your items that controls if the item should be selectable or not.
Select strategies
Data-tables support three different select strategies.
| Strategy | Description |
|---|---|
'single' | Only a single row can be selected. The select all checkbox in the header is not shown |
'page' | Multiple rows can be selected. Clicking on the select all checkbox in the header selects all (selectable) rows on the current page |
'all' | Multiple rows can be selected. Clicking on the select all checkbox in the header selects all (selectable) rows in the entire data set |
