Sticky Header Component

Overview

The sticky header component is responsible for rendering additional grid header and grid toolbar.

Sticky header is displayed when the persistent header gets hidden during vertical scrolling. The persistent header reactivates when you scroll back up:

Enable sticky header for a grid

To enable the sticky header functionality for a certain grid, declare it as a child element in the grid configuration file using the following notation:

    <container name="sticky">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="component" xsi:type="string">Magento_Ui/js/grid/sticky/sticky</item>
                <item name="toolbarProvider" xsi:type="string">...</item>
                <item name="listingProvider" xsi:type="string">...</item>
            </item>
        </argument>
    </container>

Where the following should be specified:

  • toolbarProvider: full name of the toolbar component on this page.
  • listingProvider: full name of the listing (grid) component on this page; the one for which the sticky header is enabled.

Example

Enabling a sticky header for the CMS pages grid, configured in <Magento_Cms_module_dir>/view/adminhtml/ui_component/cms_page_listing.xml:

<listing xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
        <container name="listing_top">
         ..
        </container>
        <container name="sticky">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="component" xsi:type="string">Magento_Ui/js/grid/sticky/sticky</item>
                    <item name="toolbarProvider" xsi:type="string">cms_page_listing.cms_page_listing.listing_top</item>
                    <item name="listingProvider" xsi:type="string">cms_page_listing.cms_page_listing.cms_page_columns</item>
                </item>
            </argument>
        </container>
    </listing>

Sticky header configuration

Any component of a sticky header can use a particular, not default template. This template is set in the stickyTmpl option. If the sticky template is not set, the default component’s template is used for displaying in a sticky header.

Example The toolbar component should use the ui/grid/sticky/toolbar template for the sticky header. <Magento_Cms_module_dir>/view/adminhtml/ui_component/cms_page_listing.xml:

<listing xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
        <container name="listing_top">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="template" xsi:type="string">ui/grid/toolbar</item>
                    <item name="stickyTmpl" xsi:type="string">ui/grid/sticky/toolbar</item>
                </item>
            </argument>
            ..
        </container name="listing_top">
    </listing>
