Hi CZ,


Greetings from Syncfusion support.


Query 1: How to change the Slider color?


You can customize the color of the Slider component by following any one of the below ways. The first way is to change the component's default theme to another built-in theme.


Built-in Themes : https://ej2.syncfusion.com/vue/documentation/appearance/theme/


Another way is to use a Theme Studio to generate custom themes with the required colors based on your requirements. Refer to the following links for more details on this.


Theme studio : https://ej2.syncfusion.com/vue/documentation/appearance/theme-studio/


Query 2: How to change the default min and max values for the Slider component?


You can get and set the minimum and maximum values of the Slider component by using the min and max properties. Also, the value property is used to denote the current value of the Slider. Based on your requirements, we have prepared a sample to change the color, min, and max values of the Slider component.


Check the below code snippet.


[App.vue]

<ejs-slider id="type" :value="value" :min="minvalue" :max="maxvalue" :type="type"></ejs-slider>

 

data() {

    return {

    value: [4, 5],

    type: "Range",

    mintype: "MinRange",

    minvalue: 1,

    maxvalue: 8,

    };

},

 

<style>

    @import ../node_modules/@syncfusion/ej2-base/styles/bootstrap5.css;

    @import ../node_modules/@syncfusion/ej2-vue-inputs/styles/bootstrap5.css;

</style>


You can find the output screenshots and a sample link below.


Sample(Bootstrap5 theme) : https://codesandbox.io/s/blazing-brook-j3kl7g


Output with default theme(material)


Output with built-in theme(Bootstrap5)


Please follow our suggested way and get back to us if you need any further assistance.

     :type="type" />


data: function(){

 return {

   value: [4, 5],

   type: "Range",

   minvalue: 1,

  But if  resize browser manually, two head are showing, everything is fine

Hi CZ,


Query 1: Slider handle refreshment


We have validated your reported issue in the Vue Slider component. We suspect that the issue occurs because the Slider component is not refreshed while expanding the tree nodes. We suggest you to use the reposition method to overcome the issue by taking an instance of the Slider component inside the TreeView component's nodeExpanded event. For your reference, we have attached the sample.


Refer the below mentioned code snippets.


[App.vue]

<ejs-treeview id="treeview" :fields="fields" :nodeTemplate="treeTemplate" :nodeExpanded="onNodeExpanded">

</ejs-treeview>

 

var demoVue = app.component("treeTemplate", {…

    template: `<div>

        <div class='ejob' v-if="data.sliderComp">

            <ejs-slider id="slider" :value=data.sliderVal :type=data.types></ejs-slider></div>

        </div>`,

});

 

methods: {

    onNodeExpanded: function (args) {

    document.getElementById("slider").ej2_instances[0].reposition();

    },

}


Query 2 : Is there any way to get rid of larger circle when begin to drag a head? 


With the help of CSS selectors, you can be able to override the styles for the corresponding items. Here, we have set the background-color property as transparent for the Slider handle by using the CSS selector. For your reference, check out the below code snippet.


<style>

  #slider .e-tab-handle::after {

    background-color: transparent;

  }

</style>



Check the sample and documentation links, to know more about the Slider customization.

Hi Leo,

Thank you for your information, I make a test in our program


Query 1: Slider handle refreshment



  From our test result, reposition is undefined


Query 2 : Is there any way to get rid of larger circle when begin to drag a head? 


It works, but Is there anyway we can get ride of larger circle space?



Thanks,

CZ

Hi CZ,


Query 1: Slider handle refreshment


Basically, reposition is a method that is used to refresh the Slider handle position and it does not return any values. For that reason, you got an undefined return value. We have attached the video footage for your reference. Please check the video footage for the behavior and use the shared sample to achieve the requirement at your end.


Query 2 : Is there any way to get rid of the larger circle when beginning to drag a head?


Based on the information you provided, we were unsure about the exact requirements in the Slider component. Whether you want to reduce the slider handle's highlighted color or need to move the handle dynamically. we need some additional information to validate this further. If possible, please provide a pictorial representation of your requirements. These details will help us to check and provide a prompt solution.


Please get back to us with the requested details.

Hi CZ,


Query 1: Slider handle refreshment


We are glad that your reported query has been resolved.


Query 2 : Is there any way to get rid of the larger circle when beginning to drag a head?


From your shared details, we understand that you want to minimize the Slider component width. With the help of CSS selectors, you can be able to override the styles for the corresponding items. Here, we have reduced the width property by using the CSS selector. For your reference, check the below code snippet.


Check the below mentioned code snippets and output screenshots.


<style>

    .e-control-wrapper.e-slider-container.e-horizontal {

        width: 60%;

    }

</style >



Sample : https://codesandbox.io/s/happy-montalcini-j4izbm?file=/src/App.vue


Please check the sample and confirm whether this your requirement. Please let us know if you need any further assistance.
