javascript - bootstrap multiselect dropdown selected content break in more than one 行

Question

我正在使用 bootstrap 多选下拉列表并在下拉列表中显示所有选定的值。但现在我有很多值(value)观，所以我想把它分成不止一行。现在我喜欢下图中的它。

查看选择组选项我希望所选内容分成多行。我有以下 jquery 代码。

<script type="text/javascript">
$(document).ready(function() {
    $('#fk_group_id').multiselect({
        includeSelectAllOption: true,
        enableFiltering: true,

        buttonText: function(options, select) {
        if (options.length == 0) {
            return 'Select Groups';
        }
        else {
            var selected = '';
            options.each(function() {
                selected += $(this).text() + ', ';
            });
            return selected.substr(0, selected.length -2);
        }
    },
    });
    $('.btn-group').css({"min-width":"35%"});
});
</script>

请帮助我。

你可能想用

https://cdnjs.cloudflare.com/ajax/libs/bootstrap-multiselect/0.9.13/js/bootstrap-multiselect.min.js

添加此 CSS 以中断选择

.multiselect-selected-text{
  display: inline-block;
  max-width: 100%;
  word-break: break-all;
  white-space: normal;
}

片段

$(document).ready(function() {
        $('#example-getting-started').multiselect({
        includeSelectAllOption: true,
        enableFiltering: true,

        buttonText: function(options, select) {
        if (options.length == 0) {
            return 'Select Groups';
        }
        else {
            var selected = '';
            options.each(function() {
                selected += $(this).text() + ', ';
            });
            return selected.substr(0, selected.length -2);
        }
    },
    });
    });

.multiselect-selected-text{
    display: inline-block;
    max-width: 100%;
    word-break: break-all;
    white-space: normal;
}
