Hello. I need a checkbox column in a treegrid where will only be displayed if the value of another column is different of blank. I used the formatter function and it worked. However, when making this change the checkboxall disappeared from the header. What do I need to do to make it appear?

My code:

                $('#treegrid_faturar_bof_agente_medicao').treegrid({
                    columns: [
                        [{
                                field: 'checked',
                                formatter: function(value, row, index) {
                                    if (row.chave_faturamento != "") {
                                        return '<input type="checkbox" class="easyui-checkbox" />';
                                    }
                            }
                            },{
                                field: 'nom_item',
                                title: 'Agente X Mês',
                                width: 730
                            }
                        ]
                    ],
                    singleSelect: true,
                    checkOnSelect: false,
                    selectOnCheck: false
                });

The 'checkbox' selection is the built-in functionality in the treegrid component. Please look at this example:

https://www.jeasyui.com/demo/main/index.php?plugin=TreeGrid&theme=material-teal&dir=ltr&pitem=Custom%20CheckBox&sort=asc

If you want to custom the checkbox column, please define the 'title' property for your checkbox column.
Code:
{
field: 'checked',
title: '<input type="checkbox">',
formatter: ...
}

Thanks for your help. The built-in functionality set the checkbox next to the text. I need the checkbox in a unique column. I tested the title option but when clicking on the checkbox nothing happens (not even the check is carried out). I need the checkall/uncheckall functionality. Its possible?

Thanks a lot for the help. We have one last problem. When hiding the datagrid-cell-check, the formatting of the columns is lost (see attached image). Can you help?

}
$(function () {
$('#tg').treegrid({
columns: [[
{
field: 'checked',
checkbox: true,
styler: function (value, row) {
if (!row.chave_faturamento) {
return { class: 'hidden' };

})
})
</script>
