I am creating a mobile app using Xamarin form using PCL. A text box always hides from the keyboard in iOS, but this part is working perfectly in Android. Below is my Xaml

Can you please tell me how to stop the keyboard to hide the text box that is <Entry x:Name="txtentry" in above XAML.
It's quite a typical problem on iOS and there's a ready nuget plugin which you just need to import to your app and initialize. It will check whether the keyboard is not hiding the edited textbox and move the whole page up if it's needed.

According to the documentation you need to set up experimental flags (In your target platforms projects) for some features that the development team is judging still in experimental phase, so that you acknowledge that before using them.
On android in will be in your MainActivity class, on ios in AppDelegate Class:
Forms.SetFlags("Brush_Experimental")
You can set several experimental flags at once like:
Xamarin.Forms.Forms.SetFlags(new string[] { "SwipeView_Experimental", "Shapes_Experimental", "AppTheme_Experimental" });
Note
Make sure to call SetFlags() before Xamarin.Forms.Forms.Init()
I created a MasterDetailPage to create menu for my cross platform aplication. Some items of the menu have submenus within. I would like to show these submenus after the user tap in the menu item.
I have a table view with multiple viewcell for each menu item but i dont know how to show submenu items.

I would like to have something like this : https://imgur.com/a/7OxOvRw
First of all, I would suggest you check the answer here where I have shown the optimized and easy way of creating MasterDetail setup with Xamarin Forms.
Then I would suggest you do something like this for the Expand collapse of this do something like:
<StackLayout> // Parent Menu Item Stacklayout
.
.
<StackLayout IsVisible="{Binding ShowHideBar}">
.
.
</StackLayout>
</StackLayout>
Now either you can write a convertor or just do it through the code. I will do it without a converter.
In your HamburgerMenu's ViewModel add the property :
private bool _showHide;
public bool ShowHideBar { get{return _showHide;}
set{_showHide=value; OnPropertyChanged(nameof(ShowHideBar)); }}
Then on your Items click event add the following line of code:
ShowHideBar= !ShowHideBar;
And it will work like an Expand collapse menu
Goodluck

I would like to create a page like this: [1]: https://imgur.com/YreKQi3. But picker comes with underline and i also am not being able to display table separator line.
I tried to use tableview inside a frame but it didnt work. because frame's width is larger than table and seperator becomes invisible.

In code behind, I removed the border of picker by using custom renderer:
AndroDevil mentioned in the comment: xamarin-tip-borderless-picker :
public class BorderlessPicker : Picker
{
}
Here is the result:
