Pop over with React best practice - reactjs

I'm trying to implement a pop over that can show on any screen in the web application, using React+Redux+React router
The popover is a container, that is triggered by the application state.
But how is the best practice to do such a thing, since the background is transparent, and it should just show on any screen that is currently presented.
Should it be on top of the router, on hidden, and unhide on present? I can seem to find any example for this senario...

Popover can sit inside Root component, something like this.
<App>
<HomePage />
{shouldShowPopOver && <PopOver />}
</App>
You can dispatch { type: TOGGLE_POPOVER } action anywhere, to alter shouldShowPopOver. The styling(transparent, whole page etc) should be done through css.

You ca use react-bootstrap popover. Checkout the link

I'm using react-modal component and it works pretty well.

I have used react-modal-dialog before and it works like a charm! The benefit of this library is that you can define your <Modal> component near where the source of trigger is (some button?) and it is easy to trace the condition that determines whether the modal is displayed since it is near the trigger source.
Using this library, technically it does not matter where you put the modal component among your markup as the CSS of the modal makes it appear above all other elements.

In the full screen component, the Material Ui modal does not work

I am using react-full-screen node package to make a full screen component, however modals, popovers, and drawers do not work.
Could you please help me make a working modal within my full screen component?
Are you sure it doesn't work ? maybe your modals are well displayed but behind your fullscreen component (did you use devtool's element inspector to check the html / css to see if your modal was here ?).
You might need to enrich your modal's css to make it visible ahead of fullscreen component, a mere z-index: 2 on the modal' style could help ?

React Transition Group: What is the purpose of TransitionGroup?

I'm looking to use the React Transition Group library to animate some stuff in my React page. According to those docs, the TransitionGroup component does the following:
The <TransitionGroup> component manages a set of transition components
( and <CSSTransition>) in a list. Like with the transition
components, <TransitionGroup> is a state machine for managing the
mounting and unmounting of components over time.
Consider the example below. As items are removed or added to the
TodoList the in prop is toggled automatically by the
<TransitionGroup>.
I'm not really sure what that means or why it's important.
Also, when I modify the example code that they embed on the documentation page so that the <TransitionGroup> tags are replaced with <ul> tags everything seems to work just fine (I can remove todo items by clicking on them, I can add new todo items).
Why is <TransitionGroup> component necessary? What does it do? (And why do things appear to work just fine when I replace it with an unordered list?)
React Transition Group has some advantages over typical css animations.These are some points that are coming to my mind.
Its uses binding to change classes for a components. eg: enter, appear, enter-active, appear-active, exit, exit-active etc are all part of animation classes. This make it really interactive interms of rich animations which you can not achive otherwise.
It has advatage to unmount your component using javascript, once animation is done. So basically no extra load on your front end.
It gives your freedom to define animations which ever way you like. Either css classes or defineing your own styles with in js file.
It gives you various type of animation options. Eg: Switch Transitions, Transition Groups, CssTransitions etc.
I would suggest to keep experimenting with typical css animations and react transition group and come to your own conclusion.

How to focus in SearchBox of office ui fabric react

I am unable to make a focus inside a searchbox of Office UI Fabric React component.
I have a DialogBox where I am having a searchbox. This dialog box I trigger on button click and I wants the focus to be inside the searchbox once the dialog is there.
I have tried the mostly what is mentioned in the documentation of Office UI Fabric.
So, what I have tried uptill now:
private _searchBoxRef = React.createRef<ISearchBox>();
My SearchBox component looks like:
<SearchBox
componentRef={this._searchBoxRef}
placeholder="Ask a question"
iconProps={{ iconName: 'Chat' }} />
And in the componentDidMount hook:
this._searchBoxRef.current.focus();
I am trying to make a focus inside the searchBox.
I have followed the documentation under the link:
React Guidelines for Ref Usage
Does someboby have a clue what I am doing wrong here or something I am missing??
So, I found the answer after trying out few things.
The problem was, even though I was trying to make focus inside componentDidMount(), I found that the DOM was still not ready and my searchbox inside my modal was not there.
Two things could be done here,
Either, wait for some time with SetTimeout and then tried to make focus
Can use componentDidUpdate, if setting the state which is re-rendering the component. This might also give hickups if DOM is not ready, so keep this in mind.
Hope this will help someone.

Semantic UI react, render dropdown/modal only when it's visible?

Is there a way to delay rendering of content of dropdown/modal until it is open?
I see they are being rendered even if they are not visible until user clicks to see its contents.
The Modal component uses Portal for rendering content, while Portal renders something only if it's open. This means that the component already satisfies your conditions.
With the Dropdown component, it will be more difficult. You can control it yourself, but it means that you will need to process all events self-consciously and it will be not easy.
<Dropdown open={true} options={open && options} />

Specify html content in html and have React process this

Is it possible to have this markup in the html:
<tabs>
<tab title="a title" tab-content="content">
<tab title="a title" tab-content="content">
</tabs>
and have react take that structure and create tabs functionality from it? i.e. create a list from the tab titles and divs for the content which get switched on/off depending on which tab is active.
I've come a background in Angular so may be thinking too angular-centric.
There are a variety of ways to go about creating tabbed content in React. What I believe you're asking though - specifying the content in the html - seems counter to the "react way" of doing things. From the React docs:
Remember: React is all about one-way data flow down the component
hierarchy. It may not be immediately clear which component should own
what state. This is often the most challenging part for newcomers to
understand...
The data for a given component is passed to the DOM rather than derived from it. So I wouldn't expect a React navigation component to get its functionality from existing html content but from the props passed in from the parent component or state that it manages itself.
While you could build this yourself, you may want to look at react-router which will provide some mechanisms for client-side routing and managing tabbed content.
