How to change the selected option in the view entries dropdown using the iDisplayLength attribute

ebrenes

I want to show 20 entries so I change this attribute 'iDisplayLength' to 20, but the dropdown keeps showing "show 10 entries". How can I change the selected option in the view entries dropdown? using the same value in iDisplayLength.

Thanks.

Can you copy your table initialization routine? "iDisplayLength":20, should be the answer.

Are you also including "20" as one of your dropdown options?

"LengthMenu":[[10,20,50,100,-1],[10,20,50,100,""All""]], 
"iDisplayLength":20

I fix that issue, I'm using a custom dropdown to specify the number of rows to show in the table, so when I change the attribute "iDisplayLength":20, the original dropdown created by the dataTables changes correctly but my custom dropdown not, so I change a little bit the code in the _fnFeatureHtmlLength method, using the settings parameter I just generate the html code to my custom dropdown and append it.

div.children().append(
settings.oLanguage.sLengthMenu.replace( 'MENU', selectCustom )
).append(optionStructure);

instead of the orignal dropdown
