It is possible. Basically you make sure that when user submit the form, you gather all selections and send to server and insert into the KoolReport.

This wiki may help you to understand how to insert params to KoolReport

Without using the Inputs package, work is little extra when you have to maintain the state of selection by yourself but it is not too hard, just tedious.

FYI, we are working the next version of Inputs package which has the Select2 widget, which able to do what you ask for (dropdown, multiselect, autocomplete), if you interested, I can send you the current version of the package.

It is ok, we still keep the Inputs free for now. I will send you shortly.

I have sent you the package Inputs 1.5.0. The usage of Select2 is pretty much the same with Select.

<?php
Select2::create(array(
    "name"=>"select2",
    "dataStore"=>$this->dataStore('sale_by_month'),
    "dataBind"=>"payment_date",
    "multiple"=>true,
    "attributes"=>array(
        "class"=>"form-control",
    )
));
?>

Thank you so much for your generosity :)

For your questions:

1. I have not fully understood but as I understand now that you want to show number of selections in the Select2. If so you can use echo count($this->params["your_params"])
2. The [Select All] can be done at client-side

First, Get all the available values. This require abit server-side:

<?php
$option_values = array();
$rows = $this->dataStore("data_store_for_select2")->data();
foreach($rows as $row)
{
    array_push($option_values,$row["option_value"])
}
?>

Second, set value for select2 when button [Select All] is clicked

<script type="text/javascript">
    $('#select_all_button').click(function(){
        $('#'select2_name').val(<?php echo json($option_values); ?>).trigger('change');
    });
</script>

I guess I will make widget for the multi-select that you send me in the first post. That's way it will be exact that you need. I think the multiselect that you suggest is a good one. I will keep you update

I have put your request into the feature list already however we still have a long list above. Forgive us. Would you mind to wait about 2 weeks. Or if you want to use our Consultant Service ($25/hour), I will assign you a developer to create this widget. It will take about 3 hours to complete. However if you use this service, we only charge 1 hour only since we want to put this widget to the inputs package as well. If you agree, you may just put $25 to the tip box ( sorry that we have not had to the payment for service available now). Your widget will be done tomorrow ( the latest is Monday since it is weekend).

Sure! I have assigned developer to do it right away. I will send you in few hours.

Hi,

I've sent you the Inputs package version 2.0.0 to your email. Your request multiselect has the name BSelect. Here is the usage:

<?php
BSelect::create(array(
    "name"=>"bselect",
    "multiple"=>true,
    "dataStore"=>$this->dataStore('customers'),
    "dataBind"=>"customerName",
    "options"=>array(
        "enableFiltering"=>true,
    ),
));
?>

I hope that you are happy with our service and we are looking forward to serving you further.

Have you been able to integrate BSelect into your report? Does it work well? Please let us know.

Sure thing!

Oh, you do said about that but as I replied to your post

"I guess I will make widget for the multi-select that you send me in the first post. That's way it will be exact that you need. I think the multiselect that you suggest is a good one. I will keep you update"

We made the wrapped widget for the multi-select control that you sent me in first post with all its functionality. Not sure if that controls support "deselect all" functionality. I will have a look if it is capable of. Also I will look into the translation of Search and case sensitive issue. I will come back to you.
