MultiselectColumn component

The MultiselectColumn component implements a column with checkboxes for selecting records. It also provides controls for selecting multiple records.

MultiselectColumn is a child of the Listing component and is rendered in its view. Like any component, it can hold the sort order value, which influences the order of all its child elements.

Examples

Configure a MultiselectColumn component already used in code

Sample of code where component configurations are performed:

Current implementation:

<column name="ids" class="Magento\Ui\Component\MassAction\Columns\Column">
    <argument name="data" xsi:type="array">
        <item name="js_config" xsi:type="array">
            <item name="component" xsi:type="string">Magento_Ui/js/grid/columns/multiselect</item>
         </item>
         <item name="config" xsi:type="array">
             <item name="indexField" xsi:type="string">page_id</item>
             <item name="appendTo" xsi:type="string"></item>
         </item>
    </argument>
</column>

Example of configuration modifications:

Redefining the link to the template

<column name="ids" class="Magento\Ui\Component\MassAction\Columns\Column">
    <argument name="data" xsi:type="array">
        ...
        <item name="config" xsi:type="array">
            <item name="headerTmpl" xsi:type="string">product/grid/columns/multiselect</item>
        </item>
    </argument>
</column>

Redefining the name of the property which represents record identifier

<column name="ids" class="Magento\Ui\Component\MassAction\Columns\Column">
    <argument name="data" xsi:type="array">
        ...
        <item name="config" xsi:type="array">
            <item name="indexField" xsi:type="string">product_id</item>
        </item>
    </argument>
</column>

Redefining a property data source

<column name="ids" class="Magento\Ui\Component\MassAction\Columns\Column">
    <argument name="data" xsi:type="array">
        ...
        <item name="config" xsi:type="array">
            <item name="imports" xsi:type="array">
                <item name="rows">products_prodvider:data.products</item>
            </item>
        </item>
    </argument>
</column>

Add a new component

Instance Replacement: One Instance of a Component

Redefine the link to constructor:

<column name="ids" class="Magento\Ui\Component\MassAction\Columns\Column">
    <argument name="data" xsi:type="array">
        <item name="js_config" xsi:type="array">
            <item name="component" xsi:type="string">Magento_Products/js/grid/columns/multiselect</item>
