Its working fine, but i want that all check boxes are must be in hierarchical view. I mean First parent category check and then if it has child then show child. (Like wordpress default category display system).
Unfortunately Toolset does not have any support for customising the checkbox filter controls in the way you describe.
If you insert a hierarchical taxonomy filter as checkboxes, all of the terms are included with the same markup.
There is nothing to distinguish parent terms from child terms, which would be the basis for adding some custom JS, for example, to initially hide the child terms until a parent is selected.
One possible solution would be to add some custom PHP to generate the hierarchy of terms as an array, and then to make this array available on the front-end using the function wp_localize_script (see this guide to using it: hidden link).
You could then add custom JS to hide all child terms and only make them visible when the parent was selected.
In the first instance I suggest you request the ability to customise filter controls as required using this form, which goes straight to the product manager who assesses development priorities.
I can't write the code to do this for you, I'm afraid, if it is not something you are able to do yourself you'll need to seek a developer that can, e.g. a Toolset contractor: toolset.com/contractors.
It is still the case that Views doesn't differentiate between parent and child terms when outputting a taxonomy filter as checkboxes, unfortunately, and it doesn't provide any way to customise the filter output.
I don't have a solution for you, I'm afraid, because Views does not include any way of customising filter controls.
You would still need to create a custom solution somewhat like I described above, passing the taxonomy as an array to the front end and then manipulating the checkbox inputs generated by Views so that they, for example, added classnames to child terms that could be used to style them differently.
