How to display based on picklist month and date related records?

please help me......

HI - you need to do some thing like this:

I presume you want to display the recrods of account for the month and the year the user has selected. 

So when the user selects the date and clicks the "GO" command button the result will get updated. 

remove this below line of code:
<apex:actionSupport event="onchange" reRender="out1"/>

So now update your query so that it has the ability to select only records for the date selected by the user:

Account acc : [Select Id, Name, (Select Id, Name From Opportunities) From Account Where CreatedDate=:myDaterange]

Your date format whcih you gave given above in the code will not work if you use it in query you may have to supply the correct date format check the salesforce date formats the standard one is YYYY-MM-DD and if its DateTime field it will be YYYY-MM-DDTHH:MM:SSz. Make sure you check the parametre is not null before the query and you either assign default value as today if the field is null or you could have two query one working when the fiels has a value.
