Thanks lots Ambassadors, it is much help!

As topic that I want limited Category selection at once of Category and sub-Category so on. Thanks for any help

It is very good idea to double category tree which one for products and other one for suppliers. Thanks ~SelectShop~

Thanks for reply, and it is for back-office at porducts post/edit of section, suppliers select.

Different categories of products associated with different suppliers. Different categories of products can be grouped. But suppliers could not be grouping together such as Food Fruit ... Hundreds of suppliers are very hard to be selected. Any solution？ Thanks for help

不同的分类产品对用不同的供应商， 不同的分类产品可以分组区分， 但供应商无法分组混在一起，数百个数据在选择供应商时非常不便。 请问有什么方法解决？ 谢谢！

I enter for a supplier name in the back office. And I changed name length from 64 to 128(varchar) But error message show "size over 32"

Thanks Ant for help But It is still problem after deleted class_index.php.

As title, I find answer as below, but does not work for me. (Multilingual V1.6.1.6) https://www.prestashop.com/forums/topic/377305-is-it-possible-to-increase-the-length-of-supplier-name/ I followed 2 steps as above to change, but it is still show length over 32. Thanks for any help
