    hello – first off, let me start out by saying that html smart elements ComboBox is the most valuable and useful javascript widget i have ever found.  THANK YOU so much for providing it.

    i am dynamically creating ComboBox items and believe it will be very helpful to my clients if we can suppress/hide the drop-down arrow completely if there are indeed no items to select.    otherwise, they click & see “No items”, so i do not see a reason to display the button in such situations.

    Newbies, please remember that with or without the arrow, ComboBox is still a very powerful HTML input item.

    i was unable to find such an option, so i came up with a simple suggestion/solution:

    or perhaps i missed if this is already possible with the current set of options?

    again, thank you so much for providing  ComboBox.

    Hi,

    Would not it better if you use the smart-input in that case instead? Otherwise with CSS you can hide it. The ‘.smart-drop-down-button’ CSS class is applied to the dropdown button.

    hi Peter – thank you for your reply.

    the issue i am facing is that i am creating <span style=”text-decoration: underline;”>dynamic</span> ComboBox elements from a data source, and it is very difficult to determine ahead of time if there are going to be list items or not.

    i set up an example here of what i am thinking:  https://codepen.io/edwardsmarkf/pen/poayPbg

    for ( let tmp in document.getElementsByTagName(‘smart-combo-box’) ) {
    . . . if (!isNaN(parseInt(tmp))) {
    . . . . . . . . let comboBox = document.getElementsByTagName(‘smart-combo-box’)[tmp] ;
    . . . . . . . . if ( !comboBox.items.length) {
    . . . . . . . . . . . . comboBox.getElementsByClassName(‘smart-drop-down-button’)[0].style.setProperty(‘display’ , ‘none’ );
    . . . . . . . . . . . . // HIDE the drop-down arrows if there are no items to select
    . . . . . . . . }
    . . . . }
    }

    disregard last message please – i am going to try to see if i can get a “count” first and then try out your EXCELLENT RECOMMENDATION of using the “smart-input” instead of “smart-combo-box” when there are no line items.

    thank you.
