Scroll slider is tremble in combo

When I use combo with subload (5000 records in database) and in result 10-100 Scroll slider is tremble. But in your example it’s work fined.
Why?
Do you see this before?

I detected problem,

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I use this DOCTYPE, so it’s problem for combo.

If I use doctype from your source

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> 

it’s not correct.
If I not use DOCTYPE it’s work - But it’s not correct for My html-page.

Is it bug or…?

So, and after this I can’t click on last item of combo (((

One more thing:
dhtmlx.com/docs/products/dht … ig_db.html
Pay attantion щи the 4th parameter of method enableFilteringMode(): autosubload - (boolean) enable auto load additional suggestions on selecting last loaded option.
Make the true or false, how your combo should behave.

Also I want to specify, what method do you use of a combo filtration: server or client?

Befor you reply I use:

z.enableFilteringMode(true, "person.php", true, true);

After you reply:

z.enableFilteringMode(true, "person.php", true, false);

so, now last item is OK.
But it’s not help for Scroll slider. It’s tremble. So if I drop

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
  • Scroll slider is Ok, but my html-page is bad.

If you have ideas about problems with DOCTYPE, answer please!

To reproduce your issue we need a completed demo.
Please, make it and attach here.
Guide of creating demo:
docs.dhtmlx.com/doku.php?id=othe … leted_demo
Put your doctype in there.

My code.
If I user DTD, Scroll slider is tremble.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
					"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>
<body>
<div>
<div id="person_id" name="person_id" style="width:350px; height:30px;"></div>

<script>
	var z = new dhtmlXCombo("person_id", "person_id", 350);
	z.enableFilteringMode(true, "person.php", true, false);
	z.setOptionHeight(340); 
	
</script>
</div>
</body>
</html>

If I use this code without DTD - it’s work fined.
Where is my bug?
My browser - IE8, I can’t change another browser.

We’ve checked your sample locally in IE8. Everything works as well as in other browsers. Haven’t any trembling.

So, if in IE8 and IE9 I not use compatibility mode - yes it’s work. But if I use it - slider is tremble.
In Opera - It’s work.
I think is problem with compatibility mode.
So, can We solve this? (with compatibility mode)

Ok, I solved my problem.

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8,IE=Edge"/>

But…

But if I use content=“IE=EmulateIE7,IE=Edge” - slider is tremble.
Is it bug?

We can’t reproduce this issue: any trembling isn’t found.
Could you attach COMPLETED demo of video with your issue?

We managed to reproduce a small trembling in IE7, but it doesn’t so terrible as you have. Most likely it is a IE7 bug. In later versions of IE - all OK.
Combo component doesn’t do any manipulations with the scroll. It is browser reaction.

Ок.
