angular.module("cis2")
    .directive("cis2VCOrderCreate", directiveDefinition);

templateUrl = "sections/vc/columns/vcOrderCreate/view.html";

function directiveDefinition () {
         directive = {
        "bindToController": true,
        "controller": cis2VCOrderCreateController,           
        "templateUrl": templateUrl

            let rows   = [];
            for(var i = 1; i < 50000; i++) {
                rows.push(i);
            }
            console.log(rows);
            var clusterize = new Clusterize({
                rows: rows,
                scrollId: 'scrollArea',
                contentId: 'contentArea'

Answer №1

It is important to provide markup for the rows option. Numerical values will not suffice. As stated in the documentation:

rows
If you are manually rendering rows, pass an array of tags as strings. This method is recommended. If you want to use existing markup, simply do not specify this option.

    activate () {            
        let rows   = [];
        for(var i = 1; i < 50000; i++) {
            rows.push("<li>" + i + "</li>");  //ensure this is a string containing markup
        }
        console.log(rows);
        var clusterize = new Clusterize({
            rows: rows,
            scrollId: 'scrollArea',
            contentId: 'contentArea'
        });
