Adding Frame, Script tags to TinyMCE editor
By default, Joomla will restrict you from inserting high-risk code such as IFRAME, JAVASCRIPT, STYLE into articles for security reasons.
However, it also causes trouble when you try to insert something from a third party that you trust. Such as Maps, Youtube or Charts...
This article will show you how to insert advanced codes into articles without losing them when saving. Please make sure you know what codes you are going to add.
1. First, you need to grant permissions to the user group that can use these tags.
At the admin page, go to System > Global Configuration > Text Filtering, select the user group. If you are an administrator, the group will be Super User. Select Filter Type as No Filtering.

2. Go to Extensions > Plugins > Editor - TinyMCE > Set Use Joomla Text Filter is Yes.

3. Go to the article to add code, click Toogle Editor button. Then paste the code to add and save the article.

In case you are using another editor, you should contact their developer to resolve it. Alternatively, you can also use the Custom HTML module to insert these codes.
I ve bought the pro version, i have 5700 k2 items, and only approximately 4000 migrate successfully. When i try to rerun the migration to see if it migrates the remaining 1700, it re-migrates the already migrated, creating dublicates with differnt seo url.
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
