How to select the parent elements?

I am trying to make a sidebar that stores the last click link into the local storage and still opens the collapse links after the page reloads.
$(".clickedLink").parent().parent().css('background-color', 'green');
Could someone help me how to select elements?
Example: If I click the "PHP Advanced" link it will select the #5 & #6, also the #1 & #2. But not selecting the #3 & #4...
<a class="nav-link" aria-expanded="false">Programming</a> __#1__
<div class="collapse"> __#2__
<ul>
<li>
<a class="nav-link" aria-expanded="false">HTML</a> __#3__
<div class="collapse"> __#4__
<ul>
<li>HTML Basic</li>
<li>HTML Advanced</li>
<li>HTML Examples</li>
</ul>
</div>
</li>
<li>
<a class="nav-link" aria-expanded="false">PHP</a> __#5__
<div class="collapse"> __#6__
<ul>
<li>PHP Basic</li>
<li>PHP Advanced</li>
<li>PHP Examples</li>
</ul>
</div>
</li>
</ul>
</div>
I would appreciate it if anyone can help me out

You can do something like this. call parents('.collapse') to get all parents with given class. Then call prev() to get the links.
$('a').click(function() {
var parents = $(this).parents('.collapse');
parents.css('border-top', '1px solid red');
parents.prev().css('border-top', '1px solid blue');
return false;
});

Toggle list elements in Jquery while showing the first few elements all the time

I have a menu which has categories with subcategories. I want to show/hide the list elements but the catch is I need the first 2 elements to show all the time. I have tried to look for the solution everywhere and the closest I came was jQuery toggle show/hide elements after a certain number of matching elements
but this doesn't seem to be working for me as my filters are little more complicated. Can someone please help me with this. Clicking on 'Sub-Categories' shows/hides links.
Also i must add the default state must be collapsed.

jQuery code:

jQuery('.subCat').click(function () {
jQuery(this).prev('ul:first.level1').slideToggle();
});

To achieve expected result, use below option
jQuery('.subCat').click(function () {
jQuery(this).parent().find('li:gt(1)').slideToggle();
});
Subcategories parent
Find li greater than 1 (li's index starts from 0 )
Hide by default, using jQuery(this).find('li:gt(1)').hide()

Change your javascript that do the slideToggle as this;
jQuery('.subCat').click(function () {
var ul = jQuery(this).prev('ul:first.level1');
var li = ul.find('li:gt(1)');
li.slideToggle();
});

jQuery switching lists with same class

I created a bit complex list and I wish after clicking on element with class ".recipes", display it inside paragraph but after clicking on button prev or next, I wish to switch to previous or next element with same class name. I know already how to switch the list if they are next to each other but after putting them inside different parents it seems more complicated:
<div>
<button class="prev">prev</button>
<button class="next">next</button>
<p class="showRecipies"></p>
<ul class="listOfRecipies">
<li>
<ul class="particularRecipie">
<li class="timeOfPreparation">3:20</li>
<li class="recipies">Drinks</li>
</ul>
</li>
<li>
<ul class="particularRecipie">
<li class="timeOfPreparation">3:20</li>
<li class="recipies">Vegetables</li>
</ul>
</li>
<li>
<ul class="particularRecipie">
<li class="timeOfPreparation">3:20</li>
<li class="recipies">Meat</li>
</ul>
</li>
<li>
<ul class="particularRecipie">
<li class="timeOfPreparation">3:20</li>
<li class="recipies">Fruits</li>
</ul>
</li>
<li>
<ul class="particularRecipie">
<li class="timeOfPreparation">3:20</li>
<li class="recipies">Others</li>
</ul>
</li>
</ul>
</div>
To show clicked element:
$(".recipies").on("click", function() {
$(".recipies.active").add($(this)).toggleClass("active");
var recipieValue = $(this).text();
var showRecipies = document.querySelector(".showRecipies");
showRecipies.innerHTML = recipieValue;
});
and to show previous element with class "recipes" I got from another person on this forum is here however because classes have different parents now, it doesn't work, I thought that i can add more parents() and because of that find previous or next ".recipes" but it didn't work out:
$(".prev").click(function() {
var isFirst = $(".recipies.active").is(":first-child");
if(isFirst){
$(this).parent().find(".recipies:last").trigger("click");
} else {
$(".recipies.active").prev().trigger("click");
}
});

Check this out:
$(".recipies").on("click", function() {
$(".recipies.active").add($(this)).toggleClass("active");
var recipieValue = $(this).text();
var showRecipies = document.querySelector(".showRecipies");
showRecipies.innerHTML = recipieValue;
});
$(".prev").click(function() {
var isFirst = $(".recipies.active").text() == $($(".recipies").get(0)).text();
if (isFirst) {
$(this).parent().find(".recipies:last").trigger("click");
} else {
$(".recipies.active").parent().parent().prev().find(".recipies").trigger("click");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div>
<button class="prev">prev</button>
<button class="next">next</button>
<p class="showRecipies"></p>
<ul class="listOfRecipies">
<li>
<ul class="particularRecipie">
<li class="timeOfPreparation">3:20</li>
<li class="recipies">Drinks</li>
</ul>
</li>
<li>
<ul class="particularRecipie">
<li class="timeOfPreparation">3:20</li>
<li class="recipies">Vegetables</li>
</ul>
</li>
<li>
<ul class="particularRecipie">
<li class="timeOfPreparation">3:20</li>
<li class="recipies">Meat</li>
</ul>
</li>
<li>

JQuery display menu items one at a time

I have a menu with two menu items and I want to use JQuery to display sub-menu for each menu item when the user clicks on menu item.
What happens is both submenues are displayed (where class="dropdown-content"). How can I modify my code to just display the submenu that is
under the menu item clicked. Is there any way to do that without having to specify id?
Below is my menu:
$('.menu-item').on('click', function() {
$('.dropdown-content').toggle();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="nav-mobile">
<li class="menu-item">
<img src="images/img1.png"/>
<a class="hide-on-med-and-down white-text" href='#'><span id="lblLinks">Links</span></a>
<ul id="linksdrop" class="dropdown-content">
<li>Link1</li>
<li>Link2</li>
</ul>
</li>
<li class="menu-item">
<img src="images/img2.png"/>
<a class="hide-on-med-and-down white-text" href='#'><span>User</span></a>
<ul id="userdrop" class="dropdown-content">
<li>My Profile</li>
<li>Log Off</li>
</ul>
</li>
</ul>

you need to use children() function to toggle the children of particular DOM
so use $(this).children("ul").toggle(); to accomplish what you are looking for
$('.menu-item').on('click', function() {
$(this).children("ul").toggle();
});
.dropdown-content{
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="nav-mobile">
<li class="menu-item">
<img src="images/img1.png"/>
<a class="hide-on-med-and-down white-text" href='#'>
<span id="lblLinks">Links</span></a>
<ul id="linksdrop" class="dropdown-content">
<li>Link1</li>
<li>Link2</li>
</ul>
</li>
<li class="menu-item">
<img src="images/img2.png"/>
<a class="hide-on-med-and-down white-text" href='#'><span>User</span></a>
<ul id="userdrop" class="dropdown-content">
<li>My Profile</li>
<li>Log Off</li>
</ul>
</li>
</ul>

The main problem is you should use this to identify the li you are cliking, and then use find() to traverse downwards along descendants of DOM elements.
$('.menu-item').on('click', function() {
$(this).find(".dropdown-content").toggle();
});
.dropdown-content{
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="nav-mobile">
<li class="menu-item">
<img src="images/img1.png"/>
<a class="hide-on-med-and-down white-text" href='#'><span id="lblLinks">Links</span></a>
<ul id="linksdrop" class="dropdown-content">
<li>Link1</li>
<li>Link2</li>
</ul>
</li>
<li class="menu-item">
<img src="images/img2.png"/>
<a class="hide-on-med-and-down white-text" href='#'><span>User</span></a>
<ul id="userdrop" class="dropdown-content">
<li>My Profile</li>
<li>Log Off</li>
</ul>
</li>
</ul>

To give more information, I use Bootstrap to make a responsive navbar and I don't want to use the Javascript from Bootstrap beacuse I want to get a pure Javascript.

Ok, don't know what do you mean by pure js when you using Jquery and bootstrap (which is using Jquery as well). But add that function to your code
$(document).on('mouseover','.dropdown-toggle',function(e){
$(this).parent('li').children('ul').slideDown('fast');
});
This will open dropdown menu. For hiding it you can research more.
Also I noticed that you have several elements with same id="drop-to". Id value should be unique! Name and class can be same on multiple elements.
