Combobox popup behavior

Webix JS
1

I am using the combobox editor on datatable and I have some questions on the behavior of the popup menu.

First, if the combobox doesn’t currently have a value selected and the list is very long, the combobox popup goes to the very bottom of the list, when I would prefer it to start at the top. Is this normal behavior, or can I modify it to make it go to the top?

Secondly, I have noticed that the popup likes to fill available space on the window. If the popup is towards the bottom of my page, the popup goes up. While I understand the reason for this behavior, I would like to know if its possible to always force the popup menu to go downwards on the page.

(1) I did not succeed in repeating such behaviour, check the snippet, please http://webix.com/snippet/bb42b4c5

(2) Use advanced configuration of a combo editor to specify the needed position relative to the input: (“top”, “bottom”, “left”, “right”): http://webix.com/snippet/fbc9cef3

You can also check the sample that shows other possibilities of advanced configuration: http://localhost/webix/samples/15_datatable/04_editing/21_advanced_combo.html

Thank you for the reply. Regarding #2, I’ve noticed that if I shrink the page vertically, the popup in the snippet will still go up if it thinks there is not enough space below it. I need the popup to go downwards regardless of the space below.

We will add the ability to disable the auto-positioning the popup in oncoming Webix 3.0
