feature rquest: nested number of TOC

[hua03]

The numbers of child is independent, like:

1.
  1.
  2.
2.
  1.

Most of the time, I hope they are related, like:

1
  1.1
  1.2
  1.3
2
  2.1
  2.2

Tips: CSS method counters can be used to solve this problem, it is recommended to add an list style nested number

.dynamic-toc ol {
  counter-reset: tocCounter;
}

.dynamic-toc li {
  counter-increment: tocCounter;
}

.dynamic-toc li::marker {
  content: counters(tocCounter, '.') '  ';
}

Courtesy of sailKite#4202 in the discord for another option:

/* inside Dynamic ToC */
.dynamic-toc ol {
    list-style-type: none;
}
.dynamic-toc ol {
    counter-reset: decimal;
}
.dynamic-toc ol > li {
    display: block;
}
.dynamic-toc ol > li::before {
    content: counters(decimal, ".")  " ";
    counter-increment: decimal;
    color: var(--text-a) /* put your text var here or hardcode the color */;
}
