JoomHelper Custom HTML
This module helps you to insert the following code into the Joomla page:
- HTML
- CSS
- Javascript
----------
Why I create this module?
1. Almost templates are support this feature. However, its disadvantage is that it will apply to the entire page. Module will solve this problem.
2. With Joomla's Custom module, you can use it to insert HTML or Javascript but not with CSS. The CSS must be in the HEAD tag. In additions, some TAGS will be removed (IFRAME, SCRIPT...) for safe.
----------
How to use
Install this module through Joomla installer, then goto Extensions > Modules > JoomHelper Custom HTML > Add your content and save it.
Notice: This module compatible with Joomla 3 & 4.

I have been googling how to change the menu colours, as the black text on my purple background is not very readable. However everything I have tried to change the text colour of the Off-Canvas main menu text to white did not work.
Would you know what custom CSS I would need to change all menu items to white text (including submenus).
Probably need background colour to not be white when hovering over submenus
Any help you can provide would be gratefully appreciated (or a pointer to some useful help).
Thank you

InPre-Update Check for Joomla 5.4.4
for Off-Canvas it says
Joomla cannot detect the extension's compatibility with the target version of Joomla.
have you implemented the compatibility stuff for Joomla to upgrade extensions correctly ?
Have got two off canvas menus working (1. for tools and 2. for main menu)
However I can only get the Main menu to display the first level of menu items.
Have you any suggestions for getting the sub menu items to display ?
N.B. the menu item with sub menu items does display a down arrow, but trying to click on it only display the item at the main menu level.

That imported page keeps on saying this, but nothing further is happening...
