QUESTION
I have a blog posts page that looks similar to this: https://magnolia.com/blog/
What I want to do is when the user clicks on a category, only posts of that type display below the search. The above page accomplishes that by updating the whole page, but I want the posts to change their display to none so the page doesn't have to get reloaded every time and so the featured post stays on the page. I have a list of links that display the tags for the posts, with their IDs being the possible post tag IDs.
...ANSWER
Answered 2020-Nov-17 at 16:49The easy way would be to use a javascript framework and leverage a for-each of some sort. Barring that, here's a native js way:
First off, you can't have an html id attribute start with a number. Let's assume you've prefixed all your ids with "tag_".
Javascript (uses ES6 - make note if you're supporting old browsers)
QUESTION
new to webscraping, Im using scrapy and python to grab all the categories from a specific website. The web source is included (picture of web source), and the code I've been trying is below. I am trying to isolate the categories, which fall after href="/categories#" for each of the items in the class "dropdown-submenu". I've tried
category_urls = response.css("categories").xpath("@href").extract()
category_urls = response.css(".link-list-columns").xpath("@href").extract()
but I keep getting empty columns.
any help provided is appreciated, thank you!
...ANSWER
Answered 2020-Sep-25 at 18:20I can't see any elements called "categories" and no class named "link-list-columns", so I'm not sure if the image is really the page you are scraping. (By the way, next time please don't post an image, either link the page or copy and paste the code in the question)
Assuming the print is correct, you could try:

I have a Vue component Checkbox and browsers render them on separate line. I want to have all checkboxes side by side until they wrap to new line and so on.
A generated code use block DIV but even if I changed it to SPAN there was no effect. There is too much CSS classes written by previous developer. I tried to switched them off but either it did nothing or it destroyed the rendering at all. I have extracted minimum reproducible sample at https://codesandbox.io/s/blue-currying-woeh6
The code is very large and I would rather post a small portion but people downvote the questions with incomplete sources. So I am sorry I paste it here. I recommend to open the codesandbox as it is easier to read.

QUESTION
In my Article pageModel I have an InlinePanel('technologies', label="Technologies"),
which loads up an ArticlesPageTechnologies(Orderable)
which is using PageChooserPanel('technologies', 'rb_tech_portfolio.TechnologiesPage'),
.
This is all working nicely. But what I want to do is to list links to these referenced pages, but I cannot seem to work out the best way to do this. The closest I have gotten is with {% for technology in page.technologies.all %}
but this simply gives me the object which connects the 2 page models, whereas I want the referenced object. Is this all there ready to use, or do I need to do an extra query in def_context
to do this?
Thanks, Dan
