Free sorting list with getResources?

Hi,

I want to display a list of documents using getResources sorted by the way they are sorted in the Resources list. So if the user moves a Resource (document) to another position, the list made by getResources should reflects that.

For example, my Resources list has the following ID:

Overview ID:20
Detail 1 ID:33
Detail 2 ID:34
Detail 3 ID:35

If the editor moves the resources this way:

Overview ID:20
Detail 2 ID:34
Detail 1 ID:33
Detail 3 ID:35

the list made by getResources should be exactly as this second option.

Can anybody help me to find it out?
Thank you in advance.

Add &sortby=`menuindex` to your getResources call.

Thank you odeclas for your answer.
The &sortby code seems to work but the other way around. For example, I have these Resources order:

Overview ID:20
Detail 1 ID:33
Detail 2 ID:34
Detail 3 ID:35

But in the website, the resources are displayed exactly inverse:

Overview ID:20
Detail 3 ID:35
Detail 2 ID:34
Detail 1 ID:33

Am I missing some extra code?
Thanks again.

I found it!

I just need to use the code:
&sortdir=`ASC`

Default is:
&sortdir=`DESC `
