Topic: MDB SELECT : create linked select

pro asked 5 years ago

Hi,I'm trying to add two select in a form  my website, but this two select are linked together.Let me explain this :Select1 :
  • 11 - Emballages
  • 12 - Etiquette
  • 13 - Expédition
If the user choose 11-Emballage, then  :Select2 :
  • 111 - Sale / endommagé
  • 112 - Mauvais emballage utilisé
I'm not an expert on JS or JQuery but every solution would be a huge step for me. Thx for everything,Corentin

When you select an option in the first selection and should be available second, you must remove select and then initialize it $('.mdb-select').material_select('destroy'); $('.mdb-select').material_select();

that's perfect ! thank you very much ! Can you explain me why we have to destroy a select and initialize it ? thx

When you initialized the select the first time there was only one available and only one was initialized. Then you had to delete the current select instance so that there would be no repetitions after the next select initialization.

Hi everyone,

It seems I succeed to create the two linked select as I wanted.

But I'm facing a problem with the implementation in MDB :
The code is correct and it works well without any CSS.

But when i want to had this code in my project, i have to use the class = "mdb-select". The first select is ok, but the text in the second one appears in white. You should agree that we can't see anything with white font and white background.. ^^

If anyone as solution.

Take care everyone,
