Hi Liviu, Query:  I would like to customize Select All message?We have checked your
reported query and prepared the sample based on your requirement. Please refer
the below code snippet and sample link. We can achieve your requirement by accessing
the select all div element and adding the custom text.[app.component.ts]:

onCreated(args) {
          this.listBoxObj.element.getElementsByClassName('e-all-text')[0].textContent = "Processed";
      }
   
      onChange(args) {
          if (args.event.currentTarget.classList.contains('e-selectall-parent')) {
              var proxy = this;
              setTimeout(function () {
                  proxy.listBoxObj.element.getElementsByClassName('e-all-text')[0].textContent = args.value.length === 0 ? "Processed" : "UnProcessed";
              }, 10);
          }
      }

Thank you for suggestion but it is suboptimal. The usage of setTimeout to achieve the goal is not recommended . The component on its own should have an API to expose such property and settings allowing to customize that text (Select All/ Unselect All) as well a property that will help to put a label(title) for entire list.

My final goal is to use the list box for something like the picture below:
