data-size does not work

See original GitHub issue

I have an issue while using the plugin. My problem is that when I am searching for items and there are big amount of results , vertical scrolls are not appearing. I have data-size set to 10 and it works only after I close and reopen the drop down list. Please help.

` 
$('#ddlLocation')
        .selectpicker({
        })
        .ajaxSelectPicker({
            ajax: {
                url: '@(Url.RouteUrl("Search"))',
                type: "POST",
                dataType: "json",
                data: function () {
                    var params = {
                        Filter: '{{{q}}}',
                        CountryName: 'USA'
                    };

                    return params;
                }
            },
            locale: {
                emptyTitle: 'Search for Location...'
            },
            preprocessData: function (data) {
                var i, l = data.length,
                    arr = [];
                if (l) {
                    for (i = 0; i < l; i++) {
                        if (data[i].Location.toLowerCase().indexOf(this.plugin.query) != -1 || data[i].Location.toLowerCase().indexOf(this.plugin.query) != -1) {
                            arr.push($.extend(true, data[i], {
                                text: data[i].Location,
                                value: data[i].ID,
                                disabled: false
                            }));
                        }
                    }
                }

                return arr;
            },

            preserveSelected: false,`

if fixed it by adding a setTimeout:

preprocessData: function (data) {

var arrayData = [];

[...]

setTimeout(function () {
$('#idOfSelect').selectpicker('setSize');
}, 1);

return array;
}

The issue is here in bootstrap-select: https://github.com/silviomoreto/bootstrap-select/blob/v1.12.2/js/bootstrap-select.js#L1012

} else if (this.options.size && this.options.size != 'auto' && this.$lis.not(notDisabled).length > this.options.size) {

with this part of the code: this.$lis.not(notDisabled).length > this.options.size

If using the size option and populating the options AFTER the initialization (e.g. using AJAX) the dropdown’s max height won’t be set and it will have no max height because this.$lis.not(notDisabled).length > this.options.size is false at that time as this.$lis.not(notDisabled).length will be 0 and it’s greater than this.options.size.

So this part won’t run at all:

        $menu.css({
          'max-height': menuHeight + headerHeight + searchHeight + actionsHeight + doneButtonHeight + 'px',
          'overflow': 'hidden',
          'min-height': ''
        });
        $menuInner.css({
          'max-height': menuHeight - menuPadding.vert + 'px',
          'overflow-y': 'auto',
          'min-height': ''
        });
