Accordion List with Ionic [v3]

ionic-accordion-header

An Accordion list is a very classic UI pattern, for which you can find about 100 jQuery solutions. But we want to develop an accordion list with Ionic, so we will only rely on simple JavaScript and Angular syntax for this accordion list!

If you don’t know what an accordion list is, it’s basically a list with multiple levels. You can dig into elements of the list to drill down deeper, not by opening a new page but by opening items like child items inside one item.

Once we are done with our Ionic Accordion it will look like in the image below!

    Hello
    has anyone encoutered this bug : Property ‘http’ is declared but never used.?

    1. Maike Mota says:

      This is not a Bug, the ionic compiler emits this warning when an import is never used (or called just in the html)

  5. Mangojuice says:

    Is it possible to automatically open the first level for example? So when you get to the page the drinks are already open.

    1. abdenor dexter says:

      declare open = -1;

      toggleSection(i) {

      if (this.open >= 0) {//
      this.information[this.open].open = !this.information[this.open].open;
      }

      //lecture de donnée si l’action n’est pas la fermeture de l’accordion
      if (!this.information[i].open) {……your query or TODO……..}
      if (this.open != i) {
      this.information[i].open = !this.information[i].open;
      }
      this.open = i;
      }

    2. Зорак Бракович says:

      if this.open => another.close

      Just add it to bottom of index html

  8. Curtis says:

    Hey, wonderful tutorial/walkthrough. One problem though. When you change the Direct Add Fallback from a button to a checkbox, the entire button is nothing but whitespace. As if it calculated for something, but a boolean of sorts is preventing the html that goes inside of the ion-item.
