Is there is any way to make Nav with nested links make always collapsible?
Right now I am having a huge array of INavLinkGroup[] with big amount of nested links so it looks bad when page is loaded.
Find a solution
In INavLinkGroup there is property: collapseByDefault?: boolean;

I'm currently working on a project with Nextjs and Prismic
From Prismic, I'm fetching an array of slices, which includes the navigation slice and the section slices.
I'd like to implement a full-width horizontal nav bar that starts halfway down the page, sticks to the top and automatically updates to show which section is the currently 'active' section.
Here is an example of what I mean: https://getbootstrap.com/docs/4.0/components/scrollspy/
I've built the nav bar and made it stick to the top, but am now struggling to update it with the active section.
Because each of the sections are slices, it's not possible for me use the useRef hook and get the 'ref' out of the slice and up to the page level.
An alternative I've considered is using querySelectors at the page level and using the onscroll event handler to update the class of the 'active' section. It feels a little bit hacky and I'm a little unsure of exactly how to implement it, but it's the only solution I can think of.
Could anyone please help with this?
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.
I'm about to try to create a walkthrough for a web app created using React. I'm trying to think of the best way to do it, and have been thinking of using things like Material UI's modal component. I'm thinking I should also include some kind of arrow component that points the user to whichever element (button, link, etc) on my page I want them to click next. Also I will want to create a backdrop to fade the screen except for whichever element I want the users attention to be drawn to.
I feel like this must have been done many times before, but I can't find anything from searching. Obviously whenever I Google "react walkthrough/guide/intro" I just get suggestions for teaching basic React.
(NB: I'm not looking to do one of those intro sliders, as I want to provide a more detailed step-by-step)
The keyword your need to search for is 'tour'. Searching on google for 'react tour', I found 2 libraries for you:
React Joyride: https://github.com/gilbarbara/react-joyride | Live Demo
reactour: https://github.com/elrumordelaluz/reactour | Live Demo
Both seem to have similar features:
Instruction modal that explains about an element on the page.
The modal is positioned next to the highlighted element.
The window will scroll down to the highlighted element if it's outside of the viewport.
The element is highlighted to bring more attention while the rest of the page is in the backdrop.
There are steppers on the modal to indicate which step you're on.
I am new to React. Basically, I have been given a HTML Bootstrap template. It is pretty simple... a left sidebar (always present), an adjacent menu (always present) and all other components fit adjacent to side bar and under menu. I have attached a pic so you can easily see what I mean.
I can display the components but my dynamic components or the components that change are rendered below the sidebar and NOT next to it.
I have tried to solve this issue for days... no luck. Help would be greatly appreciated.
Thank you

It seems like a css issue, make sure you have your child divs inside the parent and nothing is position absolute. if you have it online I can take a look.
I am currently using ExtJs 4.2 for developing my web pages. I would like to know whether we can define a template and can reuse the template across the pages..To be little more clear, the page header and footer remains the same across pages and only body component changes.
I mean something similar to tiles in jsp.
My scenario is like this:
I have defined a border layout in which the region="north" contains the header part, region ="south" contains the footer part and region="west" and region="center" have the body content.
All my pages have a similar layout...ie..the content at west/center is only changing across pages...so do we have solution to simplify this without defining the entire layout in all the pages...
Please let me know if further clarifications are required

I think you will want to use Ext.define, and extend the viewport component, giving it a border layout. See the ExtJS tutorial on creating custom components for how to do that. You will want to give it a border layout, and have static panels/containers/menus/toolbars for you north and south objects.
How you model your content/center and navigation/west components depends on the style of application you are building. If you are following the single page application concept with the Model/Store/View/Controller pattern that ExtJS gives you using Ext.app.Application, then you will want to drop empty containers in those slots since you can't swap out a border layout component. Putting in empty containers will allow you to call the removeAll function and then add your new items when changing views. If you are building a regular site that reloads the page whenever you move between views, you can extend the viewport that you created, and put your content directly into the viewport since it won't ever need to change.
Use define to configure a class that extends container and has the border layout you just described, so you can reuse this new class as you need.
