Magento 2 - Remove and change footer links
"About us" link and "Customer Service" link: Static block with Identifier is "footer_links_block"
To remove other links, use xml file (default.xml) and add this code into < body > tag:
<referenceBlock name="name_of_link_block" remove="true"/>
Name of link block:
Privacy and Cookie Policy: privacy-policy-link
Search Terms: search-term-popular-link
Contact Us: contact-us-link
Advanced Search: catalog-search-advanced-link
Orders and Returns: sales-guest-form-link
To add new links to footer links, use this code:
<referenceBlock name="footer_links">
<block class="Magento\Framework\View\Element\Html\Link\Current" name="your-link-name">
<arguments>
<argument name="label" xsi:type="string">Title</argument>
<argument name="path" xsi:type="string">path-of-your-page</argument>
</arguments>
</block>
</referenceBlock>
If you want to remove all the links in footer that come by default, remove the reference block.
Simply add the following link in <Vendor>\<theme>\Magento_Theme\layout\default.xml
under <body>
container
<referenceBlock name="footer_links" remove="true"/>
and in same layout file add static block so you can manage footer menu from CMS static block from magento backend
<referenceContainer name="footer">
<block class="Magento\Cms\Block\Block" name="footer_menu">
<arguments>
<argument name="block_id" xsi:type="string">footer_menu</argument>
</arguments>
</block>
</referenceContainer>
Now you can create a static block with identifier as footer_menu
You need to add
<referenceBlock name="footer_links" remove="true" />
to default.xml file
