Angularjs state routing and keeping DOM Intact - angularjs

I'm trying to create single page application and one use case is i have details page which can be triggered from multiple parent pages, more like acting as modal box but without any absolute property. I was checking how to show/hide based on the state change from parent.
This is what i have done till now

If you take a look when clicking View Home from home DOM is not removed while navigating to next state .
But if you are in About Page and click View About, DOM is getting removed.
How can we show/hide ui-view. if we are navigating to different state with same url ?

The same url
url: '^/details/:id',
for both the states is the issue.
Try having a wrapper state say "details" and then in that state's controller you may redirect based on some parameter that tells wrapper state which state to go to.

Auto Refeshing React

I am trying to implement conditional rendering for our navbar's items depending on what page we're on (i.e. If we are on the chatrooms page, or "/rooms", then we don't want the "Chatrooms" nav item to render in the navbar). What I attempted to do was convert the Navbar into a class component, create a state for the currentPage and set it to window.location.pathname, and then created methods for setting the state and what nav items to render depending on the state, but it always requires me to reload the page when going from one page to another for the conditional logic to fully take effect. Is there a better way of achieving this functionality?
You could use react-router load content without refreshing the page. It's really simple to learn and use and you could probably get it up and running within an hour. You can Add Route components for the main content of the page.
When you route to a different page you could also call a setState function and change the currentPage, which in turn changes the navbar elements.

How to resolve a state from URL using ui-router?

If I have something like this:
{ui-sref="tab({tabid:3})"}
Clicking on the element with the above attribute will trigger a state with URL something like this /tab/:tabid.
For example, http://..../tab/3
Now my problem:
I have a list of tabs implemented using angular-material. Refer this plunk
When I click on Tab1 the state is /tab/1. When I click on Tab2 the state is /tab/2. All these state changes occur with click. But now if I manually change the URL, say I type in the address bar http://..../tab/3, I want the corresponding state change to happen and Tab3 should be activated. At present, suppose I am on Tab3 and I manually change the URL to '..../tab/2', it doesn't activate Tab2, although the state is changed.
Is there a simple way to resolve states from the URL by considering the state parameters?
The main concern here is the use of tabs. The first tab belongs to one state and the remaining tabs belong to another state, each tab uniquely identified by an ID that is available through state parameter. So although the correct state is resolved when I manually change the URL, the correct tab is not not made active. The simplest workaround is to read in the state parameter using $stateParams and set the md-selected attribute of angular-material to activate the corresponding tab.

Ui router Keep page template when changing route to map state

I am trying to change the route of my url to open a map overlay. The problem is when I switch states, the page template underneath switches as well. I don't want this to happen.
I am using $statechange to detect the map route and executing an event.preventDefault(); which should stop the route template from changing. But in my case, the map url gets put in the address bar and then quickly gets removed.
Any ideas?
It seems counterintuitive to override the state change. Why don't you create the overlay as a child state and just navigate to it normally.
I managed to solve the issue by using the $state.go and declaring options 'notify' to false.. This stops the $stateroute changes to fire.

How to set default grand-child view with Angular UI Router

There is a similar question already answered (more than once) How to set default child view with Angular UI Router. I am not sure how can the answer which is based on an non-intuitive rule:
Using an empty url means that this child state will become active when its parent's url is navigated to. Urls of child states are automatically appended to the urls of their parent.
be further extended to include the solution for my case where I want the grand-child state become active when the grand-parent is selected. Specifically, I have the abstract state named 'root', then one of its first level children is named 'root.son" which has several children of its own: 'root.son.grandson1', ', 'root.son.grandson2', etc.
Here is the graphical depiction of this same situation:
Instead I want the content of the Overview tab (grandson of Health Data) to be which as the consequence of the click on Health Data Menu Item as shown below:
Note that this second image was created by clicking on the "Overview" tab in the situation depicted on the first image.

AngularJS: Two Parallel Views, One URL

I'm building a dashboard/control panel app that is basically made up of two tabs (bootstrap) at the root level, called "dispatch" and "admin". Each tab has a good bit of its own multi-tiered navigation and functionality, and they don't need to directly interact with each other. The problem I'm running into is how to deep-link to sub-views within one of the tabs without losing the "state" of the inactive tab. To clarify, I can achieve this just fine if I don't worry about updating the URL, but when I try to add deep-linking, that's when I get stuck.
An example of the desired behavior:
When you click on the "Admin" tab, the route becomes "/admin"
Click on a sub-nav item, route becomes "/admin/foo"
Select 3rd-tier sub-level item, route becomes "admin/foo/thing1"
Click on the "dispatch" tab, route becomes "/dispatch"
Click back on the "admin" tab, route goes back to "admin/foo/thing1"
So basically, if you're at the "admin/foo/thing1" route in the middle of filling out a text field, then switch to another tab, then switch back, the text field should still be there just as you left it.
Like I said, the problem isn't switching from tab to tab, since by default the tabs just show and hide things on the page without reloading any views dynamically. I just don't know how to deep-link to a given tab's "bookmarked" position when you switch to it. The way I keep thinking of it is that clicking on a tab should only update the first segment of the URL(/admin or /dispatch), and then some sort of $watch function would update the remaining segments based on the last "location" within that tab. Would something like that work?
Also, I'm using ui-router to handle all my routing and states, so I have to factor that into how I'm going to handle the desired behavior.
Help?
I worked on both those topics (deep state reactivation and parallel states) and integration into ui-router. Grab my github fork of ui-router and build using grunt. Then, mark your two tab states as parallel: true and deepStateRedirect: true.

I would just save the current state in a variable, then either dynamically change the link of the tab to whatever the last subview was.
For example, if the user is on /admin/billing, the Admin tab would link to admin/billing. When they leave that tab, the /admin tab remains the same. If you are using ui-router, you can do this with ui-srefs. You could also just manually check the variable when the state changes, and route the user there from the controller.
