Joomla website fix

Issue 1 - Fix form and Improve UI on submit article form. 1 - Please visit [login to view URL] 2 - login details will share later 3 - It will go to the new article page 4 - Kindly ADD PROFILE. 5 - Now the form comes out - kindly goto publishing tab 6 - Now add a category - you will see add the category then takes you back to the content tab - if you want to add another category you again need to goto publishing - then select another category - etc - Can you make the multi-category select easier. It is using CW multicategories - SEMI IMPORTANT 7 - IF you do the multiselect(step 6) on mobile - it doesnt work - that needs to be fixed - IMPORTANT. I also need the form UI to look nicer in general (especially on mobile view when you multi select characters for example) - NOT IMPORTANT Issue 2 - A SMALL ISSUE I noticed that the website`s RTL is not working when you press the ARABIC - LANGUAGE SWITCH link - needs to be fixed. Please quote each issue SEPARATELY. We will then assess which ones we can do.
