220 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # sv-bootstrap-dropdown (Svelte Bootstrap Dropdown) 2 | Svelte Dropdown Component for Bootstrap (Bootstrap’s dropdown plugin in svlete applications), can be used with sapper or standalone with svelte.Just like Vainilla bootstrap this plugin too is built on a third party library, [Popper.js](https://popper.js.org/), which provides dynamic positioning and viewport detection. But Unlike Vainilla bootstrap we are using PopperJs V2 instead of v1 3 | 4 | ## How to install 5 | 1. ```npm install --save-dev sv-bootstrap-dropdown @rollup/plugin-replace``` 6 | 2. Add below code in your rollup config 7 | 8 | ```js 9 | import replace from '@rollup/plugin-replace'; 10 | .. 11 | .. 12 | .. 13 | plugins: [ 14 | ..., // Other Plugins 15 | ..., // Other Plugins 16 | replace({ 17 | 'process.env.NODE_ENV': JSON.stringify('production'), 18 | include: '**/node_modules/**', 19 | }) 20 | ] 21 | ``` 22 | 23 | ### Requirements 24 | Bootstrap CSS needs to be present globally in project 25 | 26 | ## Simple Demo 27 | [Demo](https://svelte.dev/repl/f9b0e2f4193b4260b6b16bc097fa0155?version=3.23.0) 28 | ## Usage 29 | 30 | ### Single button 31 | 32 | #### Example 33 | ```html 34 | 38 | 39 | 40 | 47 |
48 | Action 49 | Another action 50 | Something else here 51 |
52 | 53 | ``` 54 | 55 | ### Split button 56 | Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of .dropdown-toggle-split for proper spacing around the dropdown caret. Just make triggerElement as splited caret button of btn-group and class `.btn-group` via classes option on Dropdown component 57 | 58 | #### Example 59 | 60 | ```html 61 | 65 | 66 | 67 | 68 | 76 |
77 | Action 78 | Another action 79 |
80 | Something else here 81 |
82 | 83 | ``` 84 | 85 | ### Trigger Sizing 86 | 87 | Button dropdowns work with buttons of all sizes, including default and split dropdown buttons as the triggerElement is being handled by the developer they have freedom to add any classes, style etc 88 | 89 | |Small|Large|Extra large| 90 | |---|---|---| 91 | | .btn-sm | .btn-lg | .btn-xl | 92 | 93 | ### Flip 94 | 95 | This option should tell the `Dropdown` to filp side if there is no space on the prefered side 96 | 97 | ### Example 98 | 99 | ```html 100 | 104 | 105 | 106 | ... 107 | 108 | ``` 109 | 110 | ### Directions 111 | 112 | Use `placement` option on `Dropdown` component for placement change 113 | 114 | --- 115 | **NOTE** 116 | 117 | > The `flip` option will take effect if there is no space for dropdown on the side mentioned in placement. 118 | 119 | --- 120 | 121 | #### Example 122 | 123 | ```html 124 | 128 | 129 | 130 | 136 |

142 | 143 | ``` 144 | 145 | #### Complete Placement Options 146 | 147 | You can use more options than Vanilla Bootstrap by using placement option 148 | 149 | |Placement|Description| 150 | |--- |--- | 151 | |auto|Placements will choose the side with most space and it will be in the center of trigger element| 152 | |auto-start|Placements will choose the side with most space and it will be in the start of trigger element| 153 | |auto-end|Placements will choose the side with most space and it will be in the end of trigger element| 154 | |top|Placements will be upside (dropup) and it will be in the center of trigger element| 155 | |top-start|Placements will be upside (dropup) and it will be in the start of trigger element| 156 | |top-end|Placements will be upside (dropup) and it will be in the end of trigger element| 157 | |bottom|Placements will be downside (dropdown) and it will be in the center of trigger element| 158 | |bottom-start|Placements will be downside (dropdown) and it will be in the start of trigger element| 159 | |bottom-end|Placements will be downside (dropdown) and it will be in the end of trigger element| 160 | |right|Placements will be rightside (dropright) and it will be in the center of trigger element| 161 | |right-start|Placements will be rightside (dropright) and it will be in the start of trigger element| 162 | |right-end|Placements will be rightside (dropright) and it will be in the end of trigger element| 163 | |left|Placements will be leftside (dropleft) and it will be in the center of trigger element| 164 | |left-start|Placements will be leftside (dropleft) and it will be in the start of trigger element| 165 | |left-end|Placements will be leftside (dropleft) and it will be in the end of trigger element| 166 | 167 | ### Responsive alignment 168 | If you want to use responsive alignment, disable dynamic positioning by using the `displayStatic="true"` attribute and use the responsive variation classes on option `menuClasses` in Dropdown component 169 | 170 | --- 171 | **NOTE** 172 | 173 | > The containing element is div and `.dropdown` is the default class on the `Dropdown` component. As it's a block-level element so width will be 100% to change use `classes` options add `.d-inline-block` or `.btn-group` so that the menu will adjust properly. 174 | 175 | --- 176 | 177 | ### Example 178 | 179 | ``` html 180 | 184 | 185 | 190 | 196 |
197 | 198 | 199 | 200 |
201 | 202 | ``` 203 | 204 | ### Offset option 205 | The offset modifier lets you displace menu element from its parent dropdown element. This option takes an array of length 2 both item of array should be Number 206 | 207 | `Ex: [10,8]` 208 | 209 | * First array Element represent `Skidding` 210 | * Seconf array Element represent `Distance` 211 | 212 | #### Example 213 | 214 | ```html 215 | 219 | 220 | 221 | 227 |

232 | 233 | ``` 234 | 235 | --- 236 | [PopperJS Documentation](https://popper.js.org/docs/v2/migration-guide/#4-remove-all-css-margins) 237 | 238 | In Popper 2 we no longer consider CSS margin because of inherent issues with it. Instead, to apply some padding between the popper and its reference element, use the offset modifier. 239 | 240 | --- 241 | Therefore we have default distance offset as 2 to have exact distance as Vanilla Bootstrap 242 | 243 | ### Component Options 244 | 245 | |Name|Type|Default|Description| 246 | |--- |--- |--- |--- | 247 | |open|boolean|false|You can use this to open the dropdown programtically from function.(*Note: setting open to true on load may lead to bug of placement in popper u can use it with displayStatic option*).| 248 | |flip|boolean|true|Allow Dropdown to flip in case of an overlapping on the reference element.
