How to implement half-circle menu (sub item) with CSS and JavaScript on mobile web? [closed]

Question

I want to use a half-circle menu when I surf the mobile web with my right hand. Can somebody teach me how to implement half-circle menu (sub item) with CSS and JavaScript on mobile web? I have tried it with CSS transform:rotate and border-radius, but it could not be worked successfully.

There is a half-circle menu button, this button can open and close menu. When I click the menu button, the main-level will be popped up. Then I click "Main 1", the sub-level (Sub 1-1, Sub 1-2, Sub 1-3) will be popped up.

As just mentioned, When I click "Main 6", the sub-level (Sub 6-1, Sub 6-2, Sub 6-3) will be popped up.

Here is the architecture of the menu:

Menu
   Main 1
      Sub 1-1
      Sub 1-2
      Sub 1-3
   Main 2
      Sub 2-1
      Sub 2-2
      Sub 2-3
   Main 3
      Sub 3-1
      Sub 3-2
      Sub 3-3
   Main 4
      Sub 4-1
      Sub 4-2
      Sub 4-3
   Main 5
      Sub 5-1
      Sub 5-2
      Sub 5-3
   Main 6
      Sub 6-1
      Sub 6-2
      Sub 6-3

Answer 1

You could do this with SVG. When you click on first-ring buttons or (Main 1, Main 2...) it will update text of second-ring buttons or (Sub 1 1, Sub 2 1...), and this is just for demo purpose. You can use js to change links inside <a xlink:href=""></a> instead of just text.

var firstRing = $('.first-ring');
var secondRing = $('.second-ring');
var siblings = firstRing.siblings('.second-ring');
var open = $('#open');

open.click(function() {
  firstRing.toggleClass('show');

  if (!firstRing.hasClass('show')) {
    siblings.removeClass('show');
  }
});

firstRing.children('g').click(function() {
  var data = $(this).data('url');
  siblings.addClass('show');

  secondRing.children('g').children('a').children('text').each(function() {
    var text = $(this).text().split(' ');
    $(this).text(text[0] + ' ' + data + ' ' + text[2]);
  });
});

svg {
  position: fixed;
  top: 50%;
  right: 0;
  transform: translateY(-50%);
  font-size: 12px;
}

g {
  fill: white;
  transition: all 0.3s ease-in;
  cursor: pointer;
}

text {
  fill: white;
}

g:not(.first-ring):not(.second-ring):hover {
  opacity: 0.6;
}

.first-ring, .second-ring {
  opacity: 0;
}

.show {
  opacity: 1;
}

.main      {fill: #2B2B2B;}
.one       {fill: #2B2B2B;}
.two       {fill: #373737;}
.three     {fill: #444444;}
.four      {fill: #515151;}
.five      {fill: #5E5E5E;}
.six       {fill: #6A6A6A;}
.sub-one   {fill: #777777;}
.sub-two   {fill: #848484;}
.sub-three {fill: #909090;}

Answer 2

No SVG, just plain css.

Basically,

• just turn rectangles over the same corner with increasing angles. Like a paper fan.
• Put the whole thing at the outermost level into a circle (border-radius:r px;overflow: hidden).
• Repeat for any further, outer rings.
• Add another outer overflow:hidden wrapper, if the enlarged last menu (‚menu 5‘) bothers you...
• Javascript is only needed, as soon as you deal with clicks and want to toggle outer rings visibility for sub-options...

This is simplified stylus syntax (similar to less, sass), see codepen➝‘view compiled’ for full css:

li
  position absolute
  top 50%
  display block
  transform-origin top right
  overflow hidden
  width r
  height r

li:nth-of-type(1)
  transform: rotate(60deg)
  background #000
li:nth-of-type(2)
  transform: rotate(40deg)
  background #222
..

Answer 3

You have to use an SVG library. Trying to make it with basic HTML elements and jQuery is probably possible using image maps, but wrapping it around jQuery will make you want to kill yourself.

I recommend d3.js since it not only handles presentation part (looks, animations) but also data with which you'll feed it.
