In order to create custom sidebar menus for my CMS pages in Magento 1, I used to be able to create a static block, and then use a widget to place it on all CMS pages that had a 2 column layout with left bar. That option is not available in Magento 2.
So, for Magento 2, I created a block called "guidenav", and I want it to appear on certain CMS pages, and for those CMS pages I can use this code in Layout Update XML:
<referenceContainer name="sidebar.additional"> <block class="Magento\Cms\Block\Block" name="guidenav"> <arguments> <argument name="block_id" xsi:type="string">guidenav</argument> </arguments> </block> </referenceContainer>
The block isn't showing up. Any ideas?
