Upgrade db scheme: php bin/magento setup:upgrade
Clear cache

But now I want to uninstall it using

sudo php bin/magento module:uninstall -r Sebwite_Sidebar

Sebwite_Sidebar is not an installed composer package

how to remove its structure database Mean to say completely remove it

Best Answer

If you installed the module manually: remove the folder app/code/<Vendor>/<Module> drop module tables from database remove the config settings.

DELETE FROM core_config_data WHERE path LIKE 'vendor_module/%'

remove the module <Vendor>_<Module> from app/etc/config.php

remove the module <Vendor>_<Module> from table setup_module

DELETE FROM setup_module WHERE module='<Vendor>_<Module>'

Then next follow the command upgrade and compile.

If you installed it via composer:

run this in console:

php bin/magento module:uninstall -r <Vendor>_<Module>

Thanks.

Magento – show categories on left side

You need to create depending on what theme are you using the folder structure as following:

app/design/Magento/theme_name/Magento_Theme/layout/default.xml where theme_name has to be changed with the current active theme ( you can find that from the Magento admin, it's "luma" or "blank" but most likely is "luma"

So your final code for that file should be:

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="2columns-left" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceContainer name="sidebar.main">
            <block class="Magento\Theme\Block\Html\Topmenu" name="catalog.topnav.aside" template="html/topmenu-aside.phtml" ttl="3600" before="-"/>
        </referenceContainer>
        <referenceBlock name="catalog.topnav" remove="true" />
    </body>
</page>

Create the following structure for removing the catalog.left nav from Layered navigation

app/design/Magento/theme_name/Magento_LayeredNavigation/layout/catalog_category_view_type_layered.xml and add the following code

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceBlock name="catalog.leftnav" remove="true" />
    </body>
</page>
