Can I link items in one list to items in parent site list in Sharepoint 2010? - sharepoint-2010

I have a parent site with several subsites in SharePoint 2010.
I have a list in the parent site (call it Product Backlog) that lists in the subsites (Sprint Backlog) need to be able to link to.
Is this possible in SharePoint 2010? That is, Can I add a lookup field in my subsite lists that points to the parent site list as the source of the data?

This is a common requirement. Event though there isn't any out-of-the-box solution, there are some workarounds for this. Check this out

I know that this field exists in document library but i don't know how i use them for specific subfolder in another list where this field will be displayed
Where and how do you want to use the count? In code, display in a list?
In a list you can edit the view and just add the "Item Child Count" column to the view.
Several code solutions here: How to find item count in a SPFolder?
If using 2013: From code using the REST API see here: https://sharepoint.stackexchange.com/questions/145219/how-to-get-itemchildcount-of-documentset-folder-using-rest-api

Need form in located in a SharePoint 2010 InfoPath web part to retain data submitted at the same time

I have created a form for use during a meeting. Multiple people need to click approve at the same time. The issue is if they all are in the form at the same time, it is only going to keep the last approval and resets the fields the others have approved... as there approval was not there when the form was opened. I guess I should have seen this coming. Is there anything I can do?
Use two lists with a parent/child relationship.
You need a master list with a unique ID and a detail list where the Master ID is assigned to the new list items to define the relationship. In the Master List you can customize the display form to contain a list view of the related items in the Detail list and a link to add new items to that detail list. A little bit of JavaScript will ensure that a new item in the Detail list gets the Master item's ID assigned automatically.
Clear as mud? The SharePoint Hillbilly has a video tutorial for 2007 and 2010.
If you go through the material (the 2007 stuff is good to understand the approach), you'll find that there are two techniques, one using SharePoint Designer, the other one without SPD.
Back to your meeting: Before the meeting, create an item in the Master list. Everybody can see the item on their screen and click to create a related item in the Detail list. They can all save their related item at the same time, since these are individual list items in the Detail list. Refresh the display view of the Master list item to see everybody's replies.

SharePoint 2010 Department Wise site

I am new to SharePoint 2010 and I have to develop a portal for my company which has several departments. I've created a HomePage now I want to come up like the following navigation.
Departments
Finance
Marketing
Sales
South Zone
East Zone
What should I do now? Create Site collection as "Department"? and Finance and marketing and sales would be sub-sites? Can anyone please mention as per my hirerchy what should be the each site I mean which one should be site collection and which one should be sb-site....and also how to make this top navigation as appear to be fly-out menu rather than tab based.
Thanks
The default navigation controls in sharepoint are per site collection.
If you create different site collections the navigation controls wont show the links to the deparment sites. However you can customize the navigation controls.
This decision should not be depending on the navigation but more in the technical requirements, is each deparment going to have many users? many concurrent users? many data?
Remember that one web application can have many site collections, but the Sharepoint Database is created per Web Application, not per site collection.
For a Fly-Out Menu, you have to do it your self, you need to create a Menu webpart and replace the existing one, you need to customize the masterpage, comment the webparts related to menu and put yours there.
