How to process a dynamic form using vue.js

Question

So I'm building a filter option for my website and its options are loaded from DB and because of this, I believe I can't use a normal v-model to do the job.

I have different filter parameters such as Categories and Companies and their options are loaded from DB so they can have 5 or 10 options.

Screenshot of the filter in the website (Better for visualization):

My code:

body {
    position: relative;
  }

  .save_filter{
    height: 40px;
  }

  .save_filter button {
    background: black;
    color: white;
    width: 100%;
    height: 100%;
    border: 0;
    border-radius: 5px;
    cursor: pointer;
  }

  .see_offer{
    position: absolute;
    bottom: 0;
    width: 100%;
    height: 50px;
    background-color: black;
    border-bottom-left-radius: 5px;
    border-bottom-right-radius: 5px;
  }

  .see_offer span{
    position: relative;
    left: calc(50% - 39.93px);
    top: calc(50% - 9.2px);
    color: white;
  }

  .main-body {
    max-width  : 1270px;
    font-family: "Ubuntu", sans-serif;
    margin     : 0 auto;
  }

  .page-content {
    padding-top: 70px;
    position   : relative;
    margin     : 0 auto;
  }

  .page-content .container {
    display        : flex;
    justify-content: space-evenly;
  }

  .page-content .first-section .category-title span {

    letter-spacing: 0.21em;
    color         : #1D1D25;
    position      : relative;
  }

  .page-content .first-section .category-title span::after {
    content      : "";
    display      : block;
    position     : absolute;

So my question is how can I get the input values independently of the number of options loaded from the database?

Answer 1

You can use v-model for this, you just need a separate array to store the selected options. Here is an example in the Vue docs.

For your case you'll need to set a value of the inputs element for the field you want to use, then can use v-model to store the selected inputs.
