I am trying to create product forms with dynamically populated lists with relevant options for selection by data entry officers. The test-case I am using is stocking computer hardware and software. If the item ‘Type’ is Hardware, the ‘Category’ list should filter out Software categories and vice-versa. I am attempting to use the ‘Select list’ syntax for a “list depending on another complementary attribute list”, with the Category list structured as: > desktop,Desktop|options\_type:hardware > workstation,Workstation|options\_type:hardware > laptop,Laptop|options\_type:hardware > tablet,Tablet|options\_type:hardware However, the Category list does not dynamically update subject to the selection of the Type list. Can anyone advise whether the select list syntax I am using is correct, or should I be using an alternative field type than ‘Select list’ in order to achieve dynamic lists, or whether this is a bug? _Category complimentary attribute_ ![image](https://www.dolibarr.org/forum/uploads/dolibarrorg/original/2X/b/b0ad092c7535da650d1aedb05d8c4c5fb4def77d.png) ---

As can be seen below, the Category list is not updated dependent upon the selection of the Type list. ---

_Type: Software - Category list still shows all entries (4x Hardware)_ ![image](https://www.dolibarr.org/forum/uploads/dolibarrorg/original/2X/a/aa0bf01ecc7eedc385526a78ecabe0f3736139b5.png) ---

The Category list also saves incorrectly: ![image](https://www.dolibarr.org/forum/uploads/dolibarrorg/original/2X/1/172a682cd24b3e232e16bf2c7c40f04388e07e02.png) ---

For those struggling with this, I finally got it to work. **My First List** Label or translation key = Catagory Attribute code = catagory Type = Select list Value = 1,CPU 2,Power Supply (Note no spaces) **My Second List** (is dependent on what is selected in the first list) Label or translation key = Spec Attribute code = spec Type = Select list Value = 1,AMD|options\_catagory:1 2,Intel|options\_catagory:1 3,750W|options\_catagory:2 4,500W|options\_catagory:2 (Note No Spaces, Use Pipe Symbol, Use underscore, Use colon) Basically we are saying If option 1 (CPU) is selected in the first list then only show AMD or Intel, If option 2 (power supply) is selected in the first list then only show 750W or 500W ---

Can anyone tell me if this feature is working in Version 20.0.3? I am not able to get the simple example above to work.
