A common problem I run into when building responsive websites is how to make a multi-level nav menu (3 or more levels) that works well for touch devices. I've seen a lot of plugins and techniques, but most of them fall flat because they don't allow a 2nd-level page to act as both a link to a page AND a parent of children in a sub-sub-menu. Some techniques address this by having an arrow icon that exposes the children menu items while clicking on the parent page name goes to the actual page... but on mobile devices these icons are usually very small targets and hence hard to use. Are there any other solutions to this problem (either jquery or javascript plugins, or straight-up CSS/JS code)?
I have a 'starting point' of sorts that I use for responsive web projects like this. I'm not sure if it's exactly what you need, but it allows for multi-level dropdown menus in desktop view. In mobile view, jQuery automatically creates an off-canvas menu.

Have you checked out any of the documentation surrounding touch-start events? I feel like you're going to get the best ux from this method. In your position, I'd be using tap to toggle classes onto your menu that would set the display to block (for example). Once your menu is open, you could then bind another touch event to the sub-level objects.
After our discussion in comments, it seems there isn't a straight forward way to get what you want due to the fact that we don't know what the user want after the submenu has been opened. There is no way for us to tell if they want to go to a link by clicking on the item again or collapse the submenu.
From this point, you have 2 options
Create a collapse once the menu is open and the user will know to use that to collapse the menu. If you think the size on most sites are small then make it bigger, however I don't think this will be an issue because it is so common.
Create a close button or something close to that for the entire menu. So when you click an item, it will expand, and if you click the same item again, it will go to the link. However there is collapsing the submenu until you click on the overall close button for the entire menu. This is only for tablets/phones as on desktop this should be a hover behaviour. This is similar to how the menu behaves on a tablet for http://www.lexus.ca. We actually have the menu closing if you click on the top most item again, you can see this behaviour on the phone or tablet. This is another option for you if the top level navs does not lead to pages.

I am using bootstrap select plugin to generate custom dropdowns in one of my projects but I am stuck in a very critical issue. The dropdown list is big and when dropdown is opened the screen moves/scrolls toward bottom a bit so that first few options can't be seen.
Issue can be seen here in this video:
https://drive.google.com/file/d/1SWQVvfOgO0-iLy0KjIf3sPEANKu8Nkpv/view
And if you want to play around please check here the color filter:

Important: I can not use the max-height or add a scrollbar to it for fixing, I must display it without scrollbar. Please anyone can help?
If I understand you correctly, the solution is for whatever reasons NOT a scrollbar, but you want the first entries of your dropdown list to stay in view, right?
Maybe JS scrollIntoView() may help: If you have the chance to apply a class to your first list entry, you could use scrollIntoView when the list opens (which is normally the case at getting the focus or on click).
You can find a short description of scrollIntoView on this page: https://www.w3schools.com/jsref/met_element_scrollintoview.asp
How can I create munu like in this site using bootstrap 4.
As you can see menu in on sidebar with categories. On mobile mode it collapsed.
I agree your question is a bit abstract but here are the main concepts you need to grasp.
With Bootstrap 4 you can create a menu from a Button Group or a Vertical Navigation.
After properly styling either of those you can have the menu suiting the design.
Regarding the collapsed version for mobile all you need is that the "hamburger button" on top toggles the sliding of the menu (using javascript, for example) and that on mobile devices the menu starts hidden using either CSS viewport rules or a javascript plugin. In fact this plugin does exactly what you need. (not affiliated)
I am using twitter bootstrap and has a very long page that I divide into multiple sections.
I'd like to implement a Section Indicator on top left of the screen that always shows where the reader is currently reading, like the screenshot below:
I managed to get the layout correctly as shown here:
However, I've got some problems that I've been working for a few weeks but still can't solved:
How to mark the current section dynamically as the user scroll
How to animate the movement of the arrow from the source to the next (or directly to the destination if the reader click a farther away rather than scrolling)
I've tried with the simpler version from getbootstrap.com/components but still to no avail... Please help... this is very stressful as I'm particularly weak in javascript and css :(
EDIT:
To summarize the answer:
Take a look at this library:
https://github.com/davist11/jQuery-One-Page-Nav.git
For a single-page website have a look at the One Page Navigation Plugin http://trevordavis.net/blog/jquery-one-page-navigation-plugin. It assigns a css-class to the current menu item upon clicking and as the user scrolls down the page.
I am designing a mobile website. On the homepage i have menu items say 'a' ,'b' ,'c',...,'h'.
I want to display only first three menu items and make a 'View All Items' button that on clicking expands to show all the items.Also the button should become 'Show Less Items' after clicking on it.
I want to do this using only HTML5 and CSS3 and no JavaScript.
Also i want this functionality to be reusable around the website.
How should i do it?
--Thanks in advance!
Modern mobile browsers all support JavaScript, but give end users (at least in Android's case, not sure about iOS) a configuration setting to disable it.
Your best bet as a developer is to use the "fail safe" strategy: Ship the HTML with the menu fully expanded, and use JavaScript to collapse the menu immediately on load (or on DOM ready). That way, if you have mobile users with JavaScript disabled, they will see the whole menu. Most of your users should have JavaScript enabled, in which case they will get the expand/collapse functionality you describe.
It's unrealistic to expect to implement this without JavaScript, and if you can find a workaround I don't believe it to be as stable as simply using JavaScript. In terms of hiding the menu items you could set their CSS property to display: none; and place a button which targets these menu items and toggles their display property.
What is the best way to display a drop down menu? for the sake of best practices.
keeping in mind:
-Accessabilty ,
Its viewable with javascript off
screen readers
-backwords capatabilty ,
viewable in IE6
-cross browser
I'm asking this because I've recently been working on some site that have css only drop down menu's that do not display the drop downs in IE6
Is displaying the drop down as a list if javascript is off the right way to do it?
The standard for javascriptless dropdown are called suckerfish or son of suckerfish dropdowns: http://htmldog.com/articles/suckerfish/dropdowns/
In IE6, though, as you'll notice, they use a little bit of js to mimic hover. That's fine--so long as the first link you hover over, that triggers the dropdown, is a real link! Have that link go to a page where they can navigate to those pages hidden in the menu. If nothing else, simply copying the submenu they're missing and making that the content of the page will work.
Voila, accessibility.
If you must ensure, it's viewable with JS turned off, go with a CSS-solution. Here's one that claims to be cross-browser:
http://lwis.net/free-css-drop-down-menu/
even though it uses a little JS for IE6 (and older).
Or maybe setup your own, using this tutorial:
