Uninstall dropdown module

Hello everybody!
I think I made a mistake on my Dolibarr v14.0.2. I installed the Drop Down Menu Module (Model c11139d20200429191903), it did not work, all the menus from the menu bar dissipated, remained just the Documents and Agenda.
I deleted the dropdownmenu directory but no use.
Can anybody help me how to uninstall the dropdown menu?
If I reinstall the v14.0.2 will it help?
Thank you

Hello,

Most probably you need to remove a constant on the database table llx_const

Hello ksar!
Thank you for the quick answer. Sadly I do not know about .sql database.
What is your opinion, If I reinstall the Dolibarr v14.0.2 will help?

Hello,

If you want to restart from zero, yes you can uninstall/re-install
