`bootstrap.css` is the core css for BootStrap that defines all the style for various controls/components, where as `bootstrap-theme.css` defines the themes (gradient/animation) for buttons,dropdown menu,navbar,progressbar,panels.

Most of the times adding `bootstrap.css` is enough for bootstrap to work, but for gradient/animation, you can use `bootstrap-theme.css`.

You can see the difference on [https://getbootstrap.com/docs/3.4/css/#buttons][1] and then click on &quot;Preview theme&quot; from the very bottom of the menu on the right-hand side of the page.

I know there isn&#39;t `MultipleChoiceField` for a **Model**, you can only use it on Forms.

Today I face an issue when analyzing a new project related with Multiple Choices.

I would like to have a field like a `CharField` with `choices` with the option of multiple choice. 

I solved this issue other times by creating a `CharField` and managed the multiple choices in the form with a `forms.MultipleChoiceField` and store the choices separated by commas.

In this project, due to configuration, I cannot do it as I mention above, I need to do it in the Models, and I prefer **NOT** to edit the *Django admin form* **neither** use forms. **I need a Model Field with multiple choices option**

- Have someone solved anything like this via Models ?

Maybe overriding some of the models function or using a custom widget... I don&#39;t know, I&#39;m kinda lost here. 

****
# Edit
I&#39;m aware off **simple** choices, I would like to have something like:

    class MODEL(models.Model):
        MY_CHOICES = (
            (&#39;a&#39;, &#39;Hola&#39;),
            (&#39;b&#39;, &#39;Hello&#39;),
            (&#39;c&#39;, &#39;Bonjour&#39;),
            (&#39;d&#39;, &#39;Boas&#39;),
        )
        ...
        ...
        my_field = models.CharField(max_length=1, choices=MY_CHOICES)
        ...
but with the capability of saving **multiple choices** not only 1 choice.


Django Model MultipleChoice

I have some problems with getting my object from a JSON string. 

I got the class `Product`

    public class Product {
        private String mBarcode;
        private String mName;
        private String mPrice;
        
        public Product(String barcode, String name, String price) {
            mBarcode = barcode;
            mName = name;
            mPrice = price;
        }

        public int getBarcode() {
            return Integer.parseInt(mBarcode);
        }

        public String getName() {
            return mName;
        }

        public double getPrice() {
            return Double.parseDouble(mPrice);
        }
    }    

From my server I get an `ArrayList&lt;Product&gt;` in JSON String representation. For example:

    [{&quot;mBarcode&quot;:&quot;123&quot;,&quot;mName&quot;:&quot;Apfel&quot;,&quot;mPrice&quot;:&quot;2.7&quot;},
    {&quot;mBarcode&quot;:&quot;456&quot;,&quot;mName&quot;:&quot;Pfirsich&quot;,&quot;mPrice&quot;:&quot;1.1111&quot;},
    {&quot;mBarcode&quot;:&quot;89325982&quot;,&quot;mName&quot;:&quot;Birne&quot;,&quot;mPrice&quot;:&quot;1.5555&quot;}] 

   
This String is generated like this:

    public static &lt;T&gt; String arrayToString(ArrayList&lt;T&gt; list) {
        Gson g = new Gson();
        return g.toJson(list);
    }
To get my Object back I use this function:

    public static &lt;T&gt; ArrayList&lt;T&gt; stringToArray(String s) {
        Gson g = new Gson();
        Type listType = new TypeToken&lt;ArrayList&lt;T&gt;&gt;(){}.getType();
        ArrayList&lt;T&gt; list = g.fromJson(s, listType);
        return list;
    }

But when calling 

    String name = Util.stringToArray(message).get(i).getName();
I get the error 
*com.google.gson.internal.LinkedTreeMap cannot be cast to object.Product*

What am I doing wrong? It looks like it created a List of LinkedTreeMaps but how do i convert those into my Product Object?

I am trying to vertically align elements within an ID wrapper. I gave the property `display:inline-flex;` to this ID as the ID wrapper is the flex container.

But there is no difference in presentation. I expected that everything in the wrapper ID would be displayed `inline`. Why isn&#39;t it?

&lt;!-- begin snippet: js hide: false --&gt;

&lt;!-- language: lang-css --&gt;

    #wrapper {
        display: inline-flex;
        /*no difference to display:flex; */
    }


&lt;!-- language: lang-html --&gt;

    &lt;body&gt;
        &lt;div id=&quot;wrapper&quot;&gt;
            &lt;header&gt;header&lt;/header&gt;
            &lt;nav&gt;nav&lt;/nav&gt;
            &lt;aside&gt;aside&lt;/aside&gt;
            &lt;main&gt;main&lt;/main&gt;
            &lt;footer&gt;footer&lt;/footer&gt;

I am experimenting with css filters.

And I would like use the blur and grayscale at the same time, but I can&#39;t seem to use both simultaneously on the same image?

See fiddle here...

    .blur {
        filter: blur(5px);
    	-webkit-filter: blur(5px);

    	-o-filter: blur(5px);
    	-ms-filter: blur(5px);
    }

I am trying to display a year range input on a form that has a 2 textboxes. One for the min and one for the max and are separated by a dash. 

I want this all on the same line using bootstrap, but I cannot seem to get it to work correctly.

Display two fields side by side in a Bootstrap Form

Ok, so everyone knows you can make a triangle using this:

    #triangle {
        width: 0;
        height: 0;
        border-left: 50px solid transparent;
        border-right: 50px solid transparent;
        border-bottom: 100px solid red;
    }

And that produces a solid, filled in triangle. But how would you make a hollow-type arrow-like triangle, like this?

![an arrow with only two lines that intersect at the point. Like a greater than sign: &gt;][1]

How to Make A Chevron Arrow Using CSS?

I&#39;m going to start new project using AngularJS (full stack). My project needs to be responsive and I&#39;ll be creating templates from scratch. 

So I need an advice on whether to choose bootstrap 3 (with angular directives) or material design for layouts? 

I&#39;d greatly appreciate if someone can list the pros &amp; cons of both.

How to remove this horizontal scrollbar in Bootstrap 3

I have a viewer with a control bar consisting of divs in a row. The other items have the FA icon already over the text for it so there is no issue with screen size but in order to differentiate two of the buttons that have higher level control to switch the content in the viewer. They are laid out as shown below:

    &lt;i class=&quot;fa fa-toggle-right lg&quot;&gt;&lt;/i&gt; &lt;span style=&quot;font-size:18px;&quot;&gt;Next

When this is shown on a small screen like an iPhone, the icon moves over the text and I&#39;d like it to stay next to it instead. The reason being that the other button then lines up with the icon below it which is bad looking UI.

    Previous&lt;i class=&quot;fa fa-toggle-left lg&quot;&gt;&lt;/i&gt;

Any options as to how to keep them from wrapping?
